Add the following lines at the end of the my.ini file and then save the file: #Disabling MySQL Strict Mode on the Server #sql-mode= "STRICT_TRANS_TABLES,NO_ZERO_IN_DATE" sql-mode="" #default_authentication_plugin=caching_sha2_password default_authentication_plugin = mysql_native_password #Turn off Derived Table Merging Flags optimizer_switch = derived_merge=off

  4. Restart MySQL.

Step 2: Install Apache 2.4

To install Apache 2.4 in ProcessMaker, follow the next steps:

  1. Download the Apache 2.4.x VC14 binary file (64-bit version) from the Apache Haus or Apache Lounge page.

    • Apache Haus:

    • Apache Lounge:

  2. After downloading Apache 2.4, create a folder with the name opt and extract the file to C:\opt.

  3. Before installing Apache, edit the Apache file httpd.conf located at C:\opt\Apache24\conf\httpd.conf.

    Change the lines:

    Define SRVROOT "/Apache24" ServerRoot "${SRVROOT}"


    Define SRVROOT "C:/opt/Apache24" ServerRoot "${SRVROOT}"
  4. Save the changes and close the httpd.conf file.

  5. Add the Apache path to the Windows environment variables. Run cmd.exe as administrator and execute the following command:

    setx /M PATH %PATH%;C:\opt\Apache24\bin
  6. In the command line (Remember to run cmd.exe as administrator), proceed to install Apache.

    cd C:\opt\Apache24\bin httpd -k install httpd -k start
  7. To enable the necessary modules for ProcessMaker, we need to run as administrator the following commands:

    cd C:\opt\Apache24\conf\ powershell -Command "(gc httpd.conf) -replace '#LoadModule alias_module modules/', 'LoadModule alias_module modules/' | Out-File -Encoding UTF8 httpd.conf" powershell -Command "(gc httpd.conf) -replace '#LoadModule deflate_module modules/', 'LoadModule deflate_module modules/' | Out-File -Encoding UTF8 httpd.conf" powershell -Command "(gc httpd.conf) -replace '#LoadModule expires_module modules/', 'LoadModule expires_module modules/' | Out-File -Encoding UTF8 httpd.conf" powershell -Command "(gc httpd.conf) -replace '#LoadModule rewrite_module modules/', 'LoadModule rewrite_module modules/' | Out-File -Encoding UTF8 httpd.conf" powershell -Command "(gc httpd.conf) -replace '#LoadModule vhost_alias_module modules/', 'LoadModule vhost_alias_module modules/' | Out-File -Encoding UTF8 httpd.conf" powershell -Command "(gc httpd.conf) -replace '#LoadModule headers_module modules/', 'LoadModule headers_module modules/' | Out-File -Encoding UTF8 httpd.conf" powershell -Command "(gc httpd.conf) -replace '#LoadModule filter_module modules/', 'LoadModule filter_module modules/' | Out-File -Encoding UTF8 httpd.conf" powershell -Command "(gc httpd.conf) -replace '#LoadModule access_compat_module modules/', 'LoadModule access_compat_module modules/' | Out-File -Encoding UTF8 httpd.conf" powershell -Command "(gc httpd.conf) -replace '#LoadModule authnz_ldap_module modules/', 'LoadModule authnz_ldap_module modules/' | Out-File -Encoding UTF8 httpd.conf" powershell -Command "(gc httpd.conf) -replace '#LoadModule ldap_module modules/', 'LoadModule ldap_module modules/' | Out-File -Encoding UTF8 httpd.conf" powershell -Command "(gc httpd.conf) -replace '#LoadModule ssl_module modules/', 'LoadModule ssl_module modules/' | Out-File -Encoding UTF8 httpd.conf"
  8. Restart the Apache service in the Service Manager or by using the following command in the console.

    cd c:\opt\Apache24\bin httpd -k restart

Step 3: Install PHP 7.4

To download the PHP binary file, click the PHP Download link and download a similar zip file,, with the last PHP version.

To install PHP 7.4, follow the next steps:

  1. Decompress the .zip file content in C:\opt, and rename the PHP folder as C:\opt\php.

  2. In the C:\opt\php, change the name of the file php.ini-development to php.ini.

  3. Reopen the Apache file httpd.conf located at C:\opt\Apache24\conf\httpd.conf, and add the following lines to the end of the file.

    LoadModule php7_module "c:/opt/php/php7apache2_4.dll" AddHandler application/x-httpd-php .php PHPIniDir "C:/opt/php"
  4. Do these changes in the php.ini file.

    • Set the following configurations: short_open_tag = On post_max_size = 24M upload_max_filesize = 24M date.timezone = America/New_York expose_php = Off memory_limit = 256M extension_dir = "c://opt/php/ext/" extension=bz2 extension=curl extension=fileinfo extension=gd2 extension=gettext extension=gmp extension=imap extension=ldap extension=mbstring extension=exif ; Must be after mbstring as it depends on it extension=mysqli extension=openssl extension=pdo_mysql extension=pdo_odbc extension=pdo_sqlite extension=shmop extension=soap extension=sockets extension=sqlite3 extension=xsl zend_extension=opcache
    • Add or set the following configuration for opcache: expose_php = Off ; Determines if Zend OPCache is enabled for the CLI version of PHP opcache.enable_cli=0 ; The maximum number of keys (scripts) in the OPcache hash table. ; Only numbers between 200 and 100000 are allowed. opcache.max_accelerated_files=10000 ; The maximum percentage of "wasted" memory until a restart is scheduled. opcache.max_wasted_percentage=5 ; When this directive is enabled, the OPcache appends the current working ; directory to the script key, thus eliminating possible collisions between ; files with the same name (basename). Disabling the directive improves ; performance, but may break existing applications. opcache.use_cwd=1 ; When disabled, you must reset the OPcache manually or restart the ; webserver for changes to the filesystem to take effect. opcache.validate_timestamps=1 ; If enabled, a fast shutdown sequence is used for the accelerated code opcache.fast_shutdown=1
    • Save the changes and close the php.ini file.
  5. Copy and paste the DLL files: libssh2.dll, libsasl.dll, libcrypto-1_1-x64.dll, and libssl-1_1-x64.dll to System32 and SysWOW64 directories.

  6. Add the PHP path to windows environment variables by running cmd.exe as administrator, and run the following command:

    setx path "%path%";"C:\opt\php" exit
  7. Stop and start the Apache service to apply the previous changes to the php.ini and httpd.conf. Run the following command in the console.

    cd C:\opt\Apache24\bin httpd -k stop httpd -k start

Step 4: Install and Configure NSSM

To install and configure the NSSM Supervisor, follow the next steps:

Note: Check if ProcessMaker files have the correct owner and permissions.

  1. Download the latest version of the NSSM application from

  2. After decompressing the contents of the zip file, copy the nssm.exe file to the folder C:\opt\. This file could be placed anywhere, but it is recommended to place all related to ProcessMaker in the same place.

  3. Open the Windows console as administrator and go to C:\opt\.

  4. Run the command.

    nssm install processmaker-jobs-<WORKSPACE>

    Specify the workspace where the jobs will run. For example:

    nssm install processmaker-jobs-workflow
  5. The last command displays a window with several tabs. Go to the Application tab.

    • In the Path field, enter the path where the PHP executable is located, usually C:\opt\php\php.exe.
    • In the Startup directory field, enter the path where ProcessMaker is installed, usually C:\opt\processmaker.
    • In the Arguments field, enter the queue command specifying the workspace. processmaker artisan queue:work --workspace=<WORKSPACE>

  6. Go to the Details tab. In the Display name field, enter ProcessMaker Jobs for <WORKSPACE>. This value helps ProcessMaker identifies jobs easily in the Windows Services Panel.

  7. Save the configuration. It is not necessary to modify the other fields.

  8. Start the service by running the following command.

    nssm start processmaker-jobs-<WORKSPACE>

    Specify the workspace, for example:

    nssm start processmaker-jobs-workflow

    Alternatively, you can open the Windows Services Panel, look for the created service and stop and start it:

  9. Depending on the Company’s security policies, additionally, in the Log on tab, you can configure the account that will run the service.

Recommended Step - Tuning Server

It is recommended to modify the hosts that is located at C:\Windows\System32\drivers\etc\hosts: localhost ::1 localhost #Also you can add here your domain ->

To apply changes, restart the network services.

cd c:\opt\Apache24\bin httpd -k restart

Also is recommended to be sure in php.ini, the following value max_execution_time = 60.
