Tracy,

Just a WAG, but I ran into a "Silent Failure" of Regsvr32 the other day on a Win10 Pro system. I would run         regsvr32 /s thecontrol.ocx from within my application's folder where the OCX files were located...then when my app tried to use the controls, it would throw an error.

I got it to work by adding the explicit path of the OCX control to the command line. In other words

regsvr32 /s "c:\myprogram\thecontrol.ocx"

worked.

Go figure. Hope this helps.

Eric,

I wish I could just put it into the local folder. However, ActiveX controls don't work that way.

I have unregistered the control, and registered the control after, restarted, uninstalled Symantec Endpoint and tried it all again. Same problem. I manually created some of the registry values to attempt to get around the problem. It still persist. I say some, because the DLL has several COM classes in it. I created an EXE that creates the control differently and it works: Form.CreateObject("test", "oleobject","activexserver.class")

But my main project has it in a Classlib, with some additional code in it. No code in the INIT of the oleControl. The error that form gets is "Class is not registered". Which I see in the Registry it isn't, until I manually put those key parts it to get the other one working. Still get the same error in the main project.

Trying other things, but this one is challenging.

Thank you, Tracy

I'm not sure, especially if the result says it registered successfully. Can you just put the control in the app's default folder so it can be found?

I've encountered this problem in the past, sometimes highlighting the shortcut, right click and Run As Administrator fixed trhe registration problem.

There have been many workstations that the ActiveX dll registered during the install. There have been many workstations that the ActiveX dll did not register during the installation. A good dozen other ActiveX / COM dll's did register during installation. This CRViewer.dll dated 1/21/2017 is the viewer for Crystal Reports. (not many using it in the VFP world) The one workstation where I've hit this wall is a Windows 7 32-bit machine. IT has it locked down, but we were using a local admin, and later the network admin user. Most of the ActiveX / COM dll's that are part of and needed by our implementation of Crystal Reports work. This Viewer ActiveX dll fails to register.

In an Administrator: Command Prompt running the following command says it is successful. C:\Windows\system32>regsvr32 "\Program Files\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\common\Crystal Reports 2011\crystalreportviewers\ActiveX Controls\CRViewer.dll"

But the CrystalReports13.ActiveXReportViewer.1 key is not found in the registry where it belongs under HKEY_CLASSES_ROOT.

Running this on other Windows 7 32-bit, Windows 7 64-bit, Windows 10 32-bit, Windows 10 64-bit systems enables the control.

I use the INNO installer for the main installation. The required C++ runtimes are installed successfully during the process. Then I register all the ActiveX / COM dlls after the C++ runtime is completed.

Works on 98 out of 100 machines. Some sites have 1 machine that has a problem and 7 others that don't. Other sites have the problem on every machine, but the manual command above fixes them.

I have not found a "common" factor of all the workstations that presented the problem of the installer failing to register the DLL.

Registering this DLL on a functioning Windows 7 32-bit machine creates 132 keys and sets 61 values in the registry. (according to ProcMon from SysInternals) I have not determined how many registry keys or values are created (if any) on the machine that fails.

This particular customer has had 4 out of 5 workstations fail to register this file on the Install. 1 machine RegSvr32 command fixed it. I have not attempted it on the other 2.

My week is over, and I've been in all sorts of directions today.

Thank you, Tracy

You could tell us which OS the workstations had, 32-bit or 64-bit.

You could tell us which ActiveX control it is, which version, age, etc.

You could tell us what you know about the workstation, make, model, color, etc. If more than one, anything in common, well, besides color...

You could tell us whether these machines are brand new or are old boxes upgraded from Windows 8.

You could tell us if they were up-to-date on patches.

You mention turning off anti-malware, good, that's often an issue.

Were there any messages in the event log?

I guess these days we can assume much of this stuff, but you know what happens when you ASSuME.

Guess #2, if this is only one workstation: Registry is corrupt

Guess #3, some sort of anti-malware protection that prevents Registry entries, like a corporate Policy setting, as many malwares wedge themselves in there good.

Guess #4, the malware's already on the machine, and IT is preventing Registry entries!

That's it, time for more coffee. Happy Friday!

The list I looked at all showed the manual regsvr32 command returned an error. My situation doesn't.

I'll set a time with the customer next week and see if there is something missing.

Thank you, Tracy

A simple google for "CRVIEWER INSTALL PROBLEM" reveals a lot of solutions. Most of them are pointing to missing subcomponents of the crviewer.dll. You could use the DEPENDECY tool to look for missing components of the viewer on those PCs. http://www.dependencywalker.com/
