Internal Error 2739 in Vista

While trying to install Open Worbench in Windows Vista, I came across this annoying problem. Every time I tried to run the installer I kept getting “internal error 2739” message and the installation process would terminate. At first I thought the setup file itself was corrupt. But on enabling MSI logging feature I learned that 2739 was MSI error code for “Could not access JavaScript runtime for custom action”. So I tried reinstalling jscript.dll.

cd c:\windows\system32
regsvr32 jscript.dll   

and it worked. 😉   

Note: For users running Vista x64, you need to reregister different version of jscript.dll file, the one that is in the WINDOWS\SysWOW64 folder
cd c:\Windows\SysWow64
regsvr32 jscript.dll
