Hello, and thank you in advance for reading. It's a bit of a long problem.

Basically, two years ago, I was running on the latest version of the software, and this for a year thanks to a student license only offering me the basic functionalities. The following year, I updated the license and updated the software to the version that had just been released, and after a month, I don't know why, it was no longer possible to use SW and a persistent message was showing ''older version of drilling assistance detected, please select installation method'' with the download box grayed out in the installation manager and unable to select where to install the damn toolbox (the ''modify'' button is also grayed out and impossible to click on it).

This year passes and I make do with another computer.

Except that, and this is where it gets bad, I manually uninstalled all solidworks at the start of the year, I don't have another computer, and when trying to reinstall solidworks (2022-2023), they don't tell me does not ask to enter a key at the start of the installation, and the problem that I encountered with the location of the toolbox repeats itself. Add to that the fact that I am not asked for a key and that the key provided by my establishment allows me this time to access a whole bunch of features, I find myself unable to install solidworks.. ...but with the wrong tools (I can't check them in the installation manager either) and without being asked to enter a key!!!

I'm good at computers, but when I uninstalled it before the start of the year, I made sure that there was nothing relating to solidworks on my computer in the software... everything that there are SW files (parts and assemblies, drawings) relating to another project....

So a big thank you in advance to anyone who knows how to help me, I've been looking for a week and trying things but it still doesn't work...

PS: sorry for writing such a poor english, i'm french...
