open TELEMAC-MASCARET The mathematically superior suite of solvers

Recently I installed the v8P4 version of TELEMAC. I was trying to simulate in parallel but I am getting an error message I do not understand. I am pasting the error message below. However, the simulation is running well in series.

Here is the log:

Even this is clearly specified and mainly spotted in the forum, you decided to install Telemac in "Program Files" directory ...

The problem is also clearly indicated in the log you copied:

something that worked for me is using the install path c:\V8P4
Also, if you have multiple versions of python installed, make sure that the python scripts in the install V8P4 directory are run by the prebuilt python in C:\V8P4\external\python-3.10.9 folder.
Last but not least, make sure that your filepath are not too long. [These were all the hiccups I had while installing and using V8P4prebuilt version in windows.

I got it...The default path for installation is c:\Program Files\...instead, the path should be changed to in c:\...
