Reinstall the application
Uninstall the application which gives you an error and install it again. During installation, pay attention to these:
1 Turn off your antivirus software before starting the installation.
2 Accept any additional software offered during installation process, since it may be crucial for running your application properly. You can skip things such as search bars, antivirus scanners, registry cleaners and the other software which isn’t directly related to the application.
3 Install an application to the system partition (C:). Although this shouldn’t matter, it’s been proven that some apps may return an error if installed on a logical partition.
Run application as administrator
Right click on your application and choose “Run as administrator”. This will give additional privileges to the application and sometimes may help fixing some errors.
If this method eliminates the error, you can set your application to always run with an administrator privileges. To do this, choose Properties from right-click menu, select Compatibility tab and check “Run this program as an administrator” option.
Run application in Windows XP compatibility mode
Try running your program in compatibility mode for Windows XP. Although this feature is for programs that were originally designed for Windows XP, it is known that it can also help repairing errors caused by a newer software.
Right click on your application and choose Properties from a right-click menu, go to Compatibility tab and select compatibility mode for Windows XP.
Check hard disk for errors
Application errors and problems may also be repaired by performing disk error checking. Simply right-click on the drive where your application is installed and choose Properties. Select Tools tab and click on Check now button. If it is your primary partition that you are trying to check for errors, it will schedule a disc check for the next system reboot. In that case, restart your PC and wait for a disk check procedure to finish.
