Standard will not install since Professional was removed
Posted on 2006-06-07
We needed to remove Adobe Acrobat 7 Professional from a PC and install a newly purchased Adobe Acrobat 7 Standard. (The professional version was going to a different PC).
1) I could not uninstall Professional using normal methods. It would give the error "The installation source for this product is not available. Verify that the source exists and that you can access it."
2) I removed the c:\program files\adobe\acrobat 7.0 directory manually
3) I rebooted and tried to install Standard, but it says "Setup has detected that you already have a more functional product installed. Setup will now terminate."
4) I tried reinstalling Acrobat Professional from the same network storage area, but now it gives the same error message as in step 1 above!
I imagine there is some registry key I can delete to fix this so that I can install Standard on the PC. But, the Adobe support area will not explain how, indicating that you must call support for help uninstalling Acrobat manually.
Thanks for any help,
