Class not registered accessing Archive Explorer

[don_sanders]

I have one user who receives the error "The XML page cannot be displayed. Class not registered" when trying to access Archive Explorer from Outlook or through IE 32-bit. It works fine using IE 64-bit. No on else is reporting the issue and the same account works fine from another computer. I've tried resetting IE settings, uninstalling/reinstalling the EV client, using another windows/archive account, resetevclient, etc. Any thoughts? Windows 7 64-bit Outlook 2010 EV 10.0.3 Lync 2010

This can occur if there was a problem registering ASP .Net.

1. Register both .Net 2.0 and 1.1 from a command line.

C:\Windows\Microsoft.NET\FrameWork\v1.1.4322\aspnet_regiis -i

C:\Windows\Microsoft.NET\FrameWork\v2.0.50727\aspnet_regiis -i

2. Run an iisreset and confirm the page can open without the error.

Use the REGSVR32 command line tool to register the following .dll:

C:\WINDOWS\System32\scrrun.dll

Hey EV_Ajay.

Isnt the instruction you provided intended for use on an EV server? If this was the issue wouldnt you see all clients having this issue...including the x64 version being tested on this client?

Don... did EV_Ajay's advise help you solve the issue?

The desktop team reimaged the computer so I wasn't able to test registering the scrrun.dll but I've saved it in case we come up with the issue again. Reimaging the system did resolve the issue for the user. Thanks.

Hi,

Reimaging the machine is always not good solution / workaround.

Hence i will recommend next time before reimage machine do the following steps and if it will not resolve the issue then go for reimage.
