Board index » Windows Vista » Error installing ActiveX cab on Windows Vista

Windows Vista34
I have a 3rd party ActiveX control I distribute with my software that fails

to install on Windows Vista. When I install it from the browser, it prompts

me to install, appears to have been successful, but the install fails

silently. Using the MS ActiveX log utility, I can see it fails with an

error: "Code Download Error: (hr = 80004005) Unspecified error".



If I manually copy this ActiveX to the target system and run regsvr32 on the

cab file, it gives me an error telling me the control "may not be compatible

with the version of Windows that you're running." If I extract the unsigned

OCX (the cab is signed; OCX is not) and run regsvr32.exe on this OCX, it

installs and runs fine.



This cab is distributed by a vendor and works on all other platforms. Oddly

enough, it only fails on SOME Vista systems.



I tried all the usual Vista tricks (added to secure zone, lowered security

in secure zone, changed Advanced IE settings related to certificates, tried

the ActiveX installer service, and disabled User Account Control).



Anyone have any pointers?

Right-click on the IE icon located on the Quick Launch

toolbar, select "Run as administrator", then attempt to install.

I'll confess that I didn't even know that feature existed... but it still

failed in the same way. Any other ideas?

Try a ng specific to the language you're using to write your app... C#? C++?

VB? Try one of those ng's...

My challenge is actually to have it loaded via a web page. I think I

mentioned before that I can manually register the OCX in the cab. What I

can't do is actually install the ActiveX from a web page via the CAB. It

fails silently. Running the Vista IE Compatibility Tool I see this (I put

X's in):



MitigationCode: ActiveXBlock

UrlPath:

UrlZone:

CLSID: {XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX}

Error: 0x800c0400

AXKill: False

ControlUrl: https://10.70.10.50/servlets/activex/XXXXX.cab

Signature: Valid

Publisher: teeMach SL

ControlUpgrade: False

ControlUpgradePath: C:\Windows\Downloaded Program Files\XXXXX.ocx

ControlUpgradePublisher:

ControlUpgradeSignature:





For some reason it seems to be treating this ActiveX differently from all

others. Any advice is appreciated.
