    Resolved [RESOLVED] Windows 10 Component Registration Issues

    Hi,

    Running VB6 IDE on Windows 10 22H2. Up until a few days ago I was able to open projects without issue. However I now receive errors when doing so.

    The issue appears to be related to some components that are not registered. There are several but for the purposes of this post I'll concentrate on MSCOMCTL.OCX.

    When I try to add this as a component to an existing project I receive an 'Object library not registered' error message.

    I can confirm the library is registered, the path is correct, and that (from googling) I have first run regtlib msdatsrc.tlb and then regsvr32 mscomctl.ocx at an administrator command prompt (both were successful).

    The above does not resolve the error.

    Any ideas?

    Thanks!

    Since this week was Microsoft's "Patch Tuesday", assuming that these patches were applied on this device, that would be one of the obvious potential culprits, based on the timing of the issue occurring.

    That being said, I would expect that if recent patches did break a bunch of .ocx functionality in W10 that there would be more reports about it here than just your post.

    Aside from potential Windows Updates, did any other software installations or upgrades take place on this device recently?

    Go here: https://www.microsoft.com/en-us/down....aspx?id=10019 grab it, grab it now. The English KB articles have already been expunged and I don't even see archive copies on 3rd party sites.

    Probably not related to 22H2 (Win 10 or Win11) but it fixes some serious bugs and is usually necessary on Win10/11 anyway. Most likely you already have it installed though if it has been working earlier.

    This seems to also be a recent issue in Microsoft Visual FoxPro.

    I updated to 22H2 on 11/2 and installed Hyper-V shortly thereafter. I have now removed 22H2, removed Hyper-V, removed IE 11 and installed the updated common controls per dilletante's post. Issue still persists. Thoughts?

    Maybe I had misunderstood. So, it had been working under Win10 22H2 and then later suddenly stopped? Or did installing 22H2 itself cause it to stop working?

    I'm not sure if it was. After removing 22H2 I noticed there are several quality updates that I am unable to uninstall which were installed on the same date. I'm thinking it has to do with one or more of those?

    When you reregustered did to make sure you were using a 32 bit version of cmd.exe from the syswow64 folder?

    I do hate how ms handled this

    I reinstalled VB6 after re-updating to 22H2 and re-adding IE11 and Hyper-V. The re-install fixed the issue and I am once again able to open my projects. Thanks to all for the suggestions.
