There are a few things that can be going on. Here are a few things I've found.
Solution 1: Clear the transaction log.
If you receive a 1935 error when you try to install Acrobat or Reader, the Windows file system transaction log has become corrupted. The transaction log is used by the Windows file system to recover when a file error occurs. To correct this install error, you need to clear the log.
a. Open an Administrator command prompt: Right-click Start > All Programs > Accessories > Command Prompt and select "Run as Administrator" and click "Allow" for the elevation prompt
b. In the command prompt, type the command below:
fsutil resource setautoreset true C:\
This assumes that C: is the drive in which Windows 7 is installed. If it is installed on another drive like D:, please change the drive letter appropriately.
c. Reboot the system.
d. Install Acrobat or Adobe Reader again. Download it from the link below: http://get.adobe.com/reader/
