What is the relationship between the pack-office and Solidworks especially that you indicate (365 around 2009)
365 would be more like 360 and around 2009 would be 2019 ;-) ;-)
So how does pack-office play on the closure of SW knowing that exchanges are essentially only done in a downward flow (SW to Word for automatic reports, maybe VBA. Excel to upstream and downstream flows).
The question is not innocent because we have seen a lot of problems related to the old versions from W7 to W10 and if it is the same for the office pack, it would be interesting (for all our colleagues) to know the ins and outs of these configurations)
I don't see the connection between the office pack and this Solidworks closure problem, but the fact remains that after this update, the solidworks closure problems have not reappeared.
Note: Until now, the use of Office 365 is not officially supported by SW (which is quite logical because Microsoft keeps updating this suite without the user being able to do anything). So basically it works but it can crash overnight following an automatic update.
At one point we had SW2014 and office 365 and clearly the 2 didn't like each other at all (frequent crashes as soon as a family of rooms is opened).
Prefer the installation of a standalone officially supported by solidworks such as Office 2019 under SW2020
