Excel 2010 VBA - Automation Error - Unspecified Error


I have a spreadsheet with some code in it, but when i try to launch one of the forms I get the error:

Compile Error:
Automation Error
Unspecified Error

The error doesn't go to any specific piece of code to give me any hints as to what the actual problem might be.

Then - I view one of the forms I have built in. When i right click on the form and select "View Code" I get the error;

Automation Error
Unspecified Error

I click OK and it is immediately followed by another dialog box with the error:

Property is write only.

I really don't know where to start... I have attached the file I am having trouble with.

I use the button on the second sheet to open the forms called "Treeview".

Thanks in advance for your help.

It works normally for me.
@MartinLiss: for me also, but only when I've restored old mscomctl.ocx (6.01.9833) and reregistered it. With new (6.01.9834) I have same error. Look at your version, please.

Hi Guys.

I thinkwe are on thr right track here - but I can't find where to download mscomctl.ocx version 6.01.9833. I do have version 6.01.9834 installed.

I have also followed the instructions to delete the .exd files from my SysWow64 directory, but now I just can't find anything newer than  version 6.01.9783 on the net.

Update: Btw - I tried using an earlier version of MSCOMCTL.OCX and registered it using regsvr32 - now I get a BIG error: as per attached jpg.

Any help appreciated.


Here is it (rename from txt to ocx). regsvr32 should be started with admin rights if you have vista or windows 7.
