Which itself version 2021 is 17,7 GB!!!nSo i was curious how the heck then this package which we have here on this laptop is only about 8 GB, and that makes about 10 GB difference (less).nAt first it thought i may be wrong, but then i realized that all previous versions are way above 12 GB size in total. So no way the 2021 version would be less. So how would this one be here only 8 GB almost.nNow this one anyway is launching, and all options in it, assumingly, are working, cause i tried to open nearly all tabs in the toolbox and those i tried, opened up, except for nRESULTS under COMPONENTS TOOLS.nI had a previous error, which i fixed, with the fluent, i had to replace some dll files and edit some permissions.nThen the client, contacted me saying results under compnonents, are not opening and returning the error that i have posted in the beginning.nAnd every sub item or sub option or sub component before and after results is opening. nI tried to open them.nAnd by far i have had spent so far more than 7 hours trying to find out why does RESULTS not open, nbut no suggestion worked, and i still cant pull it off.nWho can assist me, ni tried few commands too and nothing worked for me.nI want to know something, ndoes results open up only if the user or my client, had previously finished a certain job?nOr do i still can get to open results and pop up for me a new window even if there is nothing to show inside?nCause im starting to figure out, i mean, logically, if i can double click it, or drag and drop it, and i can open and use every option before and after results, except for this one, then probably its not a software problem, a missing file even tho i said that i found out there is around 10 GB difference in size for the installation package over the one i found on certain website along with older or previous versions. nProbably results is not opening and returning this error, cause the user has not done any work yet to see its result.nnOr else who can anyway explain to me and help me on sorting this out. Cause im really tired trying.nn

ArrayThe site you mentions must not be an ANSYS site and I would not trust downloads from a non-ANSYS site. The file sizes are different as they probably have full packages rather than STUDENT packages, which are trimmed down for the STUDENT purpose.nnRegarding the problem being encountered, this could be due to a lack of supported graphics hardware, workstation level graphics card such as Nvidia Quadro or AMD Radeon Pro / FirePro.nnThere are many posts here on the forum regarding System.ApplicationException: Application failed to connect, I would recommend searching and trying the various suggestions to see if any may work for this case.n
