The installation disc doesn't work properly.

Question

I have problems every time when I want to open a PDF file. The Lenovo technical support uninstalled the program used to open the PDF files without telling me. Now, when I want to reinstall it, the disc doesn't work properly. What can I do?

Answer 1

In order to fix the issue, press Windows + R key combination, type devmgmt.msc and click OK. Expand the Disk Drives list, right-click on the driver and select Uninstall. After that, reboot your computer, press Scan for hardware changes icon from Device Manager and wait for Windows to retrieve the drivers.

If this doesn't help, go to Start, type regedit and open the utility. Navigate to HKEY-LOCAL-MACHINE > SYSTEM > CurrentControlSet > Control > Class > {4D36E965-E325-11CE-BFC1-08002BE10318} and delete the UpperFilters and LowerFilters from the right pane. If you still have issues, I suggest you use Adobe Reader to open your PDF files. It can be downloaded free of charge from Adobe Downloads page.
