I am a student trying to uninstall the old version of SOLIDWORKS 2017 SP02 and reinstall the new version of SOLIDWORKS SP03, but got an error message of the mini Pop-Up Window saying:

"The feature you are trying to use is on a network resource that is unavailable.

Click OK to try again, or enter an alternate path to a folder containing the

installation package 'solidworks.msi' in the box below".

Then I clicked "OK" and the second error message of the mini Pop-Up Window showing:

"The file 'C:\Users\piran\Documents\SOLIDWORKS Downloads\SOLIDWORKS 2018 SP03\swwi\data\solidworks.msi' is not a valid installation package for the product SOLIDWORKS 2017 SP02. Try to find the installation package 'solidworks.msi' in a folder from which you can install SOLIDWORKS 2017 SP02".

See the attached JPG file as an example. How do I solve this problem? Thanks!
