installation of v.2.1.0 changes icon props for excell 2010

I have windows 7 Home Edition and Office 2010.

When I upgraded to Audacity v.2.1.0, I found that the icon for Excel changed its appearance to that of an unrecognised file type as per attachment.
Clicking on this icon STILL opened Excel but I couldnt understand why the icon had changed.

When I downgraded to Audacity 2.0.2, the appearance of the icon returned to normal.
Has anyone else experienced this odd behaviour?

Please don’t type all in upper case - it is generally considered to be “shouting”.

We have had one report of this issue to our feedback address, which I’m guessing was you?
There have been no other reports of this issue on either this forum or the feedback address.

There have been more than 10 million downloads of Audacity 2.1.0, so I would have expected more than one report if this was due to a bug in Audacity.

Are you using a 64 bit system?

Yes it’s the same user, so still only one report.

And I and other Team members have Excel installed and this does not happen to us.

So the answer is the same as before. There is nothing in the Audacity installer that by itself could modify Excel icons. I have made a number of suggestions to you already. Try rebuilding the icon cache or using the Registry issues cleanup in CCCleaner:

Or try uninstalling/reinstalling Excel (not just repairing it).


Yes I am the SAME user . What a surprise.

I posted this query on your forum as per a suggestion made by an MVP on the Microsoft community forum. However from the response from Steve, it would appear that I am alone in respect to this issue.

I will therefore try the other suggestions put forward.

Are you using a 64 bit system?


What difference would it make if it was 32 or 64bit?

There has been a bug affecting Office icons on 64-bit systems for years (going back to at least Office 2003 and still not fixed in Office 2010).
There’s an old post here that explains the problem and offers a fix.
I don’t use Microsoft so I can’t personally verify the fix.

I’m rather surprised that you were not able to find some reference to this bug yourself - just a quick search of Google brought up millions of hits for me.

Probably because this is a known Office bug?

Doesn’t seem to happen with Win32.

For what it’s worth I’ve installed 64-bit Windows 7 and 8 numerous times and never seen the issue, though I do only have Office 2003.

If you are experiencing the kind of bugs mentioned in the links then I agree setting a custom icon for XLS or whatever file types are affected would be a good solution.


If I may make an observation - if one doesn’t know the cause of the problem, then one may not be looking in the right place or using the ‘correct terms’ in a Google search (?) Furthermore, a good set of search results will depend on the structure of the search term.

I have borrowed a laptop running Win7 64bit and Office 2010. I will install Audacity 2.1.0 and see if I can recreated the issue. Even if I cant , if there is a bug, as you have indicated, whether or not the icon changes could be a function of the specific configuration for that machine.

Absolutely, I quite agree, but I’m far from the greatest user of Google and found loads of references to the issue straight away
I just used the terms: excel unknown icon

Finding specific useful results took a bit more hunting.

well - all the above may be irrelevant know.

When I installed Audacity 2.1.0 on my friends laptop running Win7 and Office 2010, there were NO observable issues with icon appearance or anything else.

I therefore tried to install v 2.1.0 again on my desktop and on this occasion everything went to plan and the Excel icon remained stable.

Looks like the issue resolved itself - somehow.
