This error has something to do with the incomplete installation of PC games or files of larger size. The ISDone.dll error appears due to faulty Unarc.dll file residing in the System32 folder on 32-bit operating systems and the SysWOW64 folder on 64-bit systems. So, if you see this error message, then, it means your computer was not able to read installation archive files.
winmgmt /verifyrepositoryAfter you enter the command, if there is a response saying, “repository is not consistent”, then the repository has an issue.

| Option | Recommended use |
|---|---|
| Automatically select unsigned drivers | Useful for testing on computers that are running versions of Windows that do not require signed drivers. |
| Automatically select drivers built for older versions of Windows | Useful for testing driver compatibility with newer versions of Windows. |
| Automatically select all drivers installed on this computer | Provides maximum coverage in terms of the number of drivers that are tested on a system. This option is useful for test scenarios where a driver can interact with other devices or drivers on a system. This option can also exhaust the resources available for Special Pool and some resource tracking. Testing all drivers can also adversely affect system performance. |
| Select driver names from a list | In most cases, you will want to specify which drivers to test. Selecting all drivers in a device stack allows the Enhanced I/O Verification option to track objects and check compliance because an I/O request packet (IRP) is passed between each of the drivers in the stack, which allows for a greater level of detail to be provided when an error is detected. Select a single driver if you are running a test scenario that measures system or driver performance metrics, or if you want to allocate the greatest number of resources available for detecting memory corruption or resource tracking issues (such as deadlocks or mutexes). The Special Pool and I/O Verification options are more effective when used on one driver at a time. |
