Frequently Asked Questions

What does 'procedure entry point' mean?
A procedure entry point is a specific function exported by a DLL. When an application calls that function and it does not exist in the DLL version on your system, you get this error. It means there is a version mismatch.
Can another application cause this error?
Yes. Some applications install older versions of shared DLLs that overwrite newer versions. This is known as 'DLL Hell'. Uninstalling the conflicting application or reinstalling the affected one usually resolves this.
