Description Jesus Corrius 2013-08-16 17:55:13 UTC
Warning: Writing to Windows directory, and or root directories test detected the following errors:

File C:\Windows\SysWOW64\msvcr100.dll was written to an incorrect location.
File C:\Windows\SysWOW64\msvcp100.dll was written to an incorrect location.

Apps mustn’t store data in system folders, such as %SystemDrive% or %WinDir%. Storing app and user data in a system folder can cause access and security problems for the user. Using the Known Folder APIs ensures that you are always able to get to your data.

Hi Jesús,
as I can see in the Details of the files properties:
- msvcp100.dll = Microsoft C Runtime Library
- msvcr100.dll = Microsoft C Runtime Library
what I think are installed by Microsoft C++ Redistributable, needed to run LibreOffice.

Hi Andras,

Any comment on this one? I have my theory but I would like to hear it from you :)

It is not us, who write into %WinDir%, it is the merge module of Microsoft VC Runtime. Does this mean that bundling runtime libraries via merge modules are not "recommended" any more?
Comment 4 Jesus Corrius 2013-09-03 15:26:59 UTC
I am a little bit worried for one case scenario. 

We install the C runtime libraries using the merge modules. Another third party application detects that they already exist and it doesn't install them. The user uninstalls libreoffice and this third party application doesn't work anymore.

Title does not reflect discussion and concern is expressed in Comment 4. 
While it's true LO bundles Microsoft C++ Redistributable and removes it on uninstall, listed scenario is not LO issue, so I'll mark as NotOurBug. 
Even with leaving this bug open it's not reasonable to expect a solution for such a scenario. 

If we're speaking about corporate env., my practice is to install C++ Redistributables first, and separately. 
But if there are users who have permission to remove LO they should also undertand C++ Redistributable issue and take responsibility for that.
