How to Register and Unregister DLLs and OCXs in Windows

By | January 24, 2019

We are familiar that Sage 300 ERP allows to customize the standard screens which has different OCX name than that of standard name. Whenever we perform some type of customization in Sage 300 which has new screen files and other dependent files, user needs to register the same in windows.

New Stuff: Receiving Location cost cannot exceed the defined limit in customized IC Transfer screen

There are times when we change only few files in Sage and needs to be reflected in Sage 300 ERP. Always running REGACC is not viable as Sage 300 takes few minutes to few hours depending on the modules installed in the system.

Follow the below steps to Register/Unregister single DLL/OCX:

Step 1: Run Command Prompt with Administrative Rights. Click on Start, search cmd, right click and “Run as Administrator”.

Command Prompt

Step 2: Register a DLL/OCX file using regsvr32 command with regsvr32 followed by the path of the DLL/OCX file.

Example:

regsvr32 “D:\Program Files (x86)\Sage\Sage 300 ERP\OE65A\AccpacOE1100.ocx”

Registered Ocx

Step 3: Unregister a DLL/OCX file using regsvr32 command with regsvr32 followed by the path of the DLL/OCX file.

Example:

regsvr32 /u “D:\Program Files (x86)\Sage\Sage 300 ERP\OE65A\AccpacOE1100.ocx”

Unregistered Ocx

Now the DLL/OCX has been successfully added to the windows registry and it ready to be used.
