Registering / unregistering application DLL files
Scenario
You may receive error messages that reference a specific DLL file (the file name ends with .dll) on your workstation or server. This error appears when the DLL is required for use by the application and may indicate that the DLL has not been registered correctly.
Solutions
Use the following procedures to register the a DLL.
Register / re-register files
To register or re-register an application DLL file on your workstation, follow these steps.
- ChooseStartthenRunand enterregsvr32followed by the path to the DLL file you would like to register.
You do not need to unregister a file to re-register it.
The following example is an integration DLL file that needs to be re-registered for FileCabinet CS. The file is stored in
X:\WinCSI\Cabinet\cscabsv.dll
, (where X represents the drive where FileCabinet CS is installed).In the
Run
dialog enter the following line to register cscabsv.dll.regsvr32 X:\WinCSI\Cabinet\cscabsv.dll
note
If you've installed FileCabinet CS into a folder with a label that contains a space (for example,
X:\Program Files\Winapps\Cabinet
), you must enclose the entire path, including the file name, in quotation marks, as follows.regsvr32 "X:\Program Files\Winapps\Cabinet\cscabsv.dll"
Unregister files
If you still see this error after completing the steps above, you may need to unregister the DLL file prior to re-registering it. To unregister the DLL, include
/u
followed by the DLL path, and then enter the same command without the /u
to register it again.Example
To unregister the file from the example above, enter the following into the
Run
dialog.regsvr32 /u X:\WinCSI\Cabinet\cscabsv.dll
