Serenity: PDF generator returned error code 255!

[she-ll-b-rite]

Hi all, I'm using the ReportHelper to create a PDF rendered to the browser, which is working perfectly in dev (Windows 10), but I'm getting the following error in prod environment (Windows Server 2012 R2)

Server Error in '/' Application.

PDF generator returned error code 255!

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.InvalidOperationException: PDF generator returned error code 255!

Source Error:

Stack Trace:

[InvalidOperationException: PDF generator returned error code 255!]
Serenity.Reporting.HtmlToPdfConverter.Execute() in P:\Sandbox\Serene\Serenity\Serenity.Web\Reporting\Tools\HtmlToPdfConverter.cs:164
PWB.ReportController.Execute(String key, String opt, String ext, Boolean download, Boolean printing)

Things I've checked:

• wkhtmltopdf.exe is in folder '~\App_Data\Reporting'
• App Pool account has read, write and execute permission on this folder
• App Pool account has read & write permission on '%USERPROFILE%\AppData\Local\Temp'

Any suggestions for what to check next?

Check 32 bit/64 bit. Check exe file is not blocked in properties, unblock it.

Solved! wkhtmltopdf.exe also has dependency on "Visual C++ Redistributable Packages for Visual Studio 2013" which weren't installed on the server.
