Perl error
 

Hi,

I have installed perl on a 64 bit windows os, and while running VisualBuild (perl step) I am getting following erro

Failed to instantiate script engine 'PerlScript': Class not registered

What could be the reason, cause when i run the perl script from command line it just works fine.

Best Regards

You need to install the x86 edition of ActivePerl, including the PerlScript feature.

Perl 5 Version 12 x64
 

Is there a way to get VBPro to work with MSWin32-x64-multi-thread perl?

If you're calling perl.exe from Visual Build, you can call the 32-bit and 64-bit versions.

If you're using PerlScript Active Scripting integration, that won't work with the current version of Visual Build, since it's 32-bit only, but the next version of Visual Build will also have a 64-bit edition, which will work with 64-bit ActivePerl.
