RE: Error RegSvr32

Hi Venessa,

I did some research on this and came to a conclusion which probably will solve your problem-

Assumptions:

dll (assembly is created in c# (or in .net environment and not in native com environment like vb6)

If the above assumption is true then you need follow certain guideline to avoid various different issues:

Mention assembly property:
open your custom class project in visual studio and

- Go to the property of the project and click on the 'Assembly Information' button in 'Application' tab (marked yellow)

in the screen open, check the 'Make Assembly COM visible' (marked yellow)

Build the dll

As this is created in .net environment, it can not be registered using regsvr32 and you need to use regasm command. you can find the regasm.exe in 'C:\Windows\Microsoft.NET\Framework\v2.0.50727'.

Run command prompt in administrator mode (right click and choose 'run as administrator'

in command prompt, change the folder to C:\Windows\Microsoft.NET\Framework\v2.0.50727 and run regasm as follows:

I had copied the dll file in the same folder and that's why I have not mentioned the full path of the file in the command prompt.

if you see closely, I tried to register it twice. I got an error first time ''No types were registered'. This happens if we don't mention 'Make assembly COM visible' (as described in step 1 here)

Once I made the assembly COM visible as described in step 1, my 2nd attempt to register it was successful.

Please note, all these manual registration process can be avoided using a simple step -

- Open your class project in visual studio in administrator mode (right click and say 'run as administrator')

- open the property window of the class and go to 'Build' tab

- go to the bottom of the screen and check the 'Register for COM interop' (marked yellow in bellow screenshot -

- rebuild the dll.

this time system will register the dll for you and you don't need to register it separately

it's important to run the visual studio in administrator mode otherwise, you will receive 'access denied' error'

Hope the above explanation will help you in troubleshooting your error. Do let me know if it is resolved.

Thanks

Hello Vanessa,

In case you are running a 64 bit OS. Did you check you are using the right version of regsvr? Check this link for more info: support.microsoft.com/.../282747

RE: Error RegSvr32

I just tried registering a .dll with the command and it worked. Only thing that I kept both the .dll and .tlb file in the same folder (when you created the add-in, you will have .dll as well as .tlb file)

Try putting the .tlb file along with .dll file in the same folder.

I will try some more scnario to simulate the error.

also you can refer to following link from microsoft support -

RE: Error RegSvr32

Put your dll in the same folder from where you are running the regsvr32 or

put the dll in C:\Windows\System32 folder and fire the regsvr32 again
