Steps to Fix Runtime 91 Error

To fix this error, it is important to know what is causing this error to occur. There are a number of steps involved in removing this error from PC. This can be done manually or automatically but the manual way of getting it done is not recommended if you are not a PC expert.

Step # 1:

Most of the time, this error can be fixed through a patch from the developers of that particular program causing this. These patches often prove to be helpful but if they don’t, you would need third-party Registry Cleaner software like CCleaner in order to remove the harmful files from the PC.

Windows stores all the settings that are required inside a database called registry. This database contains so many files that it can become a big issue for the Windows itself. So, using cleaner software is the best option for resolving this issue. Follow these steps below to use the registry cleaner software.

1. For the purpose of cleaning registry files, open the CCleaner application and click on Registry tab at the left side of the application.

Step # 2:

Viruses are the major cause of runtime errors. So, to avoid these errors to contaminate the whole system, use an antivirus program like Avast or Avira to clean up your system. You can download these antivirus programs from internet free of cost.

Step # 3:

There is a program in Windows i.e. DCOMCnfg.exe which controls various operation of the computer by blocking and unblocking permissions on certain files. This program can block certain files from public access leading towards runtime 91 error. So, you should change the permission inside this program to public. However; this method is not recommended for new bie users. Only advanced level users should use the DCOM Console to change permissions inside the container for the program in question (which produces the run time error 91)

I would appreciate if you let us know which method has worked if any; and if nothing worked for you so we can improve our guide.
