Solution

Solution 1 :

This problem is caused by the fm20.dll module being incorrectly registered by Windows.

This problem occurred during the installation process when Microsoft allowed multiple programs to modify the registration information of VB\VBA dll.

First, find the existence of the fm20.dll file. According to the OS version or the number of bits, it will be placed in a different path.

For 32-bit systems: C:\Windows\System32\

 a. Click the Start button
 b. Right-click, use the administrator authority to call up the command prompt window
 c. Enter Regsvr32 fm20.dll, press Enter to confirm

In the case of a 64-bit system: C:\Windows\SysWOW64\

 a. Click the Start button
 b. Right-click, use the administrator authority to call up the command prompt window
 c. Enter cd C:\Windows\SysWOW64\, execute
 d. Enter Regsvr32 fm20.dll, press Enter to confirm

After confirming by pressing Enter, the following message will appear:

DllRegisterServer in c:\windows\system\fm20.dll succeeded.

This means that Fm20.dll has been correctly registered successfully.
