Adobe Photoshop Feather LogoRight, you’ve got a shiny new copy of Adobe Photoshop CS3 in your hands and a desktop loaded with Microsoft Vista in front of you. However, each and every time you attempt to install CS3 the installer just bombs out with nary a single error message.

Not cool when you consider how much the application actually cost in the first place!

Anyway, run the installer from the command line and see if it spits out an error. If it does, and the error reads “End Adobe Setup. Exit code: 4” then you are in luck.

(Alternatively, take a look inside the Adobe log file named Add or Remove Adobe Creative Suite 3 Web Premium 1.0.log.gz. Again, if you find a line reading “DEBUG: Error 2739: Could not access JavaScript runtime for custom action Internal Error 2739” then you’re definitely in luck)

The problem is caused due to the MSI installer code running custom Jscript and to fix it one simply needs to re-register the jscript DLL file.

So without any further ado:

Open an administrive cmd prompt
cd windowssytem32
regsvr32 jscript.dll

Note: you might have to run the cmd prompt as Administrator in order to gain the necessary rights in order to re-register the offending DLL.
