A blast from the past... something somewhere installs a newer version of an ActiveX or other COM thingy, possibly in a different location, and removes the one your app used. Your app's runtime detects a missing component and requires that it be reinstated. The solution was to have your version of those in your app's folder.

I guess it wouldn't be any of those that your forms use, as these wouldn't be detected until the form is opened, so I guess it would be one of those elementary ones, like comctls.

Now which components, and specially what are their filenames, ouch... takes some time to investigate, as m$ has obfuscated the issue, the names are mostly unrelated to each other, and you need to know where to look for the relation. Since I'm generally not using anything m$ for a few years now, ... you'll manage.
