I've attempted to install 8.1.2. on Windows XP and continue to get the error messages below:
When I try to open a pdf, I first get the following:
Adobe Reader: Acro32.exe - unable to locate component
The application has failed to start because USP10.dll was not found. Re-installing the application may fix the problem.
I click OK and then the following message:
Invalid plugin detected. Adobe Reader will quit.
Then the file closes.
In one attempt to reinstall, I received error message to defragment C drive and then repair in add/install programs under control panel. Did not work. I also attempted to install on alternate drive. Defaulted back to C drive (defragment issue is in C).
