How to Fix Adobe Photoshop CS3 Error 2739 on Windows Vista
I just moved to Windows Vista and as Per my usage I had to install Photoshop CS3, But when I tried Installing I came up with the error "Internal Error 2739. Contact Adobe Customer Support"
With a little research, it turns out that the error is due to an Adobe application installer JScript compatibility issue that Adobe is looking into.
Good news, there is a quick fix to help your system bypass the Adobe Internal Error 2739 - simply register "DllRegisterServerM" in the Windows Vista system registry.
Click Start, then All Programs, then Accessories
Right click on Command Prompt and select on Run as Administrator
The command prompt will be launched with administrative rights, simply enter regsvr32 jscript.dll and press Enter
You should now see the following Windows Vista system message window pop up with the message "DLLRegisterServer in jscript.dll succeeded".
Your system is now all set and ready to install Adobe Photoshop CS3 and the rest of the Adobe Creative Suite 3 family of software programs.
