Today I tried to install Adobe CS3 on my Vista x64 workstation. The installer immediately failed with an "Internal Error 2739". There was much info to help troubleshoot the problem.
After doing some Google searches, I ran across a couple solutions. Basically, you need to register the 32-bit versions of vbscript.dll and jscript.dll from the "SysWOW64" directory.
- Jump to a Command prompt by selecting "Run as Administrator".
- cd to ..\SysWOW64
- Type regsvr32 jscript.dll
- Type regsvr32 vbscript.dll
- Re-launch your installer
Hope this helps others.
