Can't use activex controls in new installation

[oediehl]

A slightly older PC with my (complex) accdb Access program stopped working properly, and so I installed office 2021 32-bit on a new Windows 10 64-bit PC. The Access program seems to run fine on the new system, but when I go into design mode and try to insert any basic activex control (eg comdlg32.ocx), it tells me that I don't have the license required for the activex control. The ocx file is in windows\syswow64\, and I've tried again and again, as an Administrator, to regsvr32 /u uninstall and regsvr32 reinstall the c:\windows\syswow64\comdlg32.ocx file, regularly rebooting the PC between actions. It always tells me the regsvr32 action was successful, but I still can't work with activex controls in Access design mode (but the program works OK when not in design mode). Another message I sometimes get in design mode is that the OLE server should be reinstalled, but I've not been able to find out how to do that. I've been hammering away at this for 3 days now, including multiple reinstalls of Office, but even in a new Access db with nothing but a blank form, I cannot install an activex control. What the Heck is going on here?

I just installed Office 2021 and can use Access ActiveX controls. But not the comdlg32.ocx.

See if any of these fixes help https://appuals.com/how-to-fix-the-c...or-on-windows/

I will have to give them a try sometime.

Many, many years ago I had a Developer version of Office---I'm wondering if this version of 2021 I just installed does not allow the use of Activex, or something like that?

I also started getting a weird "need SourceSafe (SP?) client installed" message. I never used SourceSafe and my understanding is that it was retired close to 2 decades ago. Arggghhh

I can install other ActiveX controls, such as WebBrowser.

I finally uninstalled everything (again), and restarted by 1st installing an ancient copy of Office XP Developer, hoping that the Developer part would somehow fix my wonky OLE Server issues (even though the Access version is unusable for my project, since it uses the old mdb format). I then reinstalled Office 2021, and lo and behold, it worked! Microsoft can be awfully quirky.
