Why are Matlab.App​lication.S​ingle entries corrupted in registry?

Dear support,

I have several Matlab versions installed, and my problem is I am unable to start a new Matlab instance (Matlab.Application.Single) via COM with the version I specify what is not the last registered Matlab version.

For example:

I am exucuting a code in R2011b (7.13) that tries to start a new Matlab.Application.Single.7.13 instance. But it starts a new R2010bSP1 instance (the one I've installed lastly) rather than opening a new R2011b instance.

I have investigated the issue:

Correct entries:

• In registry in the node "Matlab.Application.Single", the CLSID is set to the class id that corresponds to R2010bSP1, and this is absolutely okay, because this is the currently registered Matlab version.
• In node "Matlab.Application.Single.7.11" it is also the correct R2010bSP1 CLSID is displayed.

Not so correct entries:

• But in the node "Matlab.Application.Single.7.13", what is the dedicated node to R2011b, the CLSID is the same as I have written above.
• This is true for R2008b also.
• For R2013b and R2014b (8.2, 8.4) in the dedicated nodes a different class id is inserted (and both of them are correct).

So as a conclusion:

• Why the installation of R2010bSP1 have corrupted my registry entries for Matlab versions older than R2013b?
• Is there a generic solution to fix the registry in an "official" way or shall I implement something to fix it (generating new CLSID-s and assign them accordingly)?
• If there is an official solution, what is that?

Thanks a lot in advance!
