Problem with installation caused by msvcr71.DLL

[MisterP]

Hi,
I have problem during the installation.

I get a message saying :
InstallShield is trying to install or unistalled a file that is currently being used by another program.

Locked file : C:\WINDOWS\system32\msvcr71.dll

click Postpone to change this file the next time you restart the computer.
Click skip to leave this file unchanged.

I have click "skip " and everything seem to work but I'm affraid that something go wrong later when I will save a project or download it in the PLC.

Anyone have an idea about this msvcr71.dll file.

Thanks,

Whenever you see this, you should click "postpone" and then reboot.  Basically, you ran the install program with another program that was still running that uses this DLL.  Many applications use Microsoft C or C++, so this is a fairly common DLL to be used.

One issue is that you have an "old" version of the DLL on your PC and this would have udated that one file.  Usually it's good to shut down all applications when you do any install.  If you ever see that error, it's best to click "postpone", skip should rarely be used unless you are intimately aware of the code in the old and the new version of the DLL.

If you see any strange behavior, you may need to reinstall the software.
