Do i need to uninstall older version of Revit to install a newer version!

[Anonymous]

Hello!

 I just want to ask if i should first uninstall my 2018 Revit App to install 2020 Version Revit? i have problems with my 2018 Revit bout the "Pick Line" tool leading to the "unrecoverable error" and forced to closed. I already read forums bout the said problem but i dont see if it is fixed already since it was posted last 2017 but no "fixed error" response. i also read and think that perhaps it was only on the 2018 version so i really want to install a newer version maybe there is no same problem already.. 'Pick Line" tool is really helpful and important to me cause i am working with my academic purpose drawn in autocad with unusual form of floor plan so the tool really helped me a lot. it really was working until it reached to 41,000+ KB in size the file itself i am working. tried to purge the file but it still no longer working tho. now i am installing 2020 version Revit but the error "The installer has detected that the following programs are running. Revit.exe" is keep stopping me from installing the newer version.. i already read tips in different forums tho they are different AutoDesk Applications it all didnt work, the task manager app closing etc., that is why i want to know if i should delete my 2018 version Revit to install the newer version. i am just scared that maybe uninstalling the older version doesnt really mean anything about the error that is stopping me from installing the newer version, that when deleted i may not be able to reinstall every version even the 2018 version. Will deleting my 2018 Revit is solution for me to be able to install the 2020 Revit? Thank You!! :)) ❤️ ❤️ 

Regards,

🙂

Unfortunately, this is not the best place to ask such a question.

Please note that this discussion forum is dedicated to programming Revit using the Revit API.

Therefore, you cannot expect an answer to a question such as yours relating to installation, product usage or end user support issues here.

You should try one of the non-API Revit product support discussion forums instead for that:

https://forums.autodesk.com/t5/revit-api-forum/this-forum-is-for-revit-api-programming-questions-not...

The people there are much better equipped to answer your question than us programming nerds.

I hope this clarifies.

Thank you for your cooperation and understanding.

That said, I can also let you know that I have never uninstalled a previous version of Revit prior to installing the new one.

They always run fine side by side for me.

I just recently installed Revit 2021 without touching my existing installation of Revit 2020, and they still both run perfectly.

Best regards,

Jeremy
