Quartus18.1PRO install error

May i know what OS that you were uisng?

Can u try to install Quartus 20.1? See if it behaves the same?

Another things to try is right click -> open with admin.

Can u try the following:

1) provide the screenshot -> my computer -> properties

2) install currprocess https://www.nirsoft.net/utils/cprocess.html and disable all the software running behind there

3) disable the anti virus

4) close all the Quartus software

go to c:/user/<username>/ rename the quartus2.ini and quartus2.req for windows

and reopen the quartus. this will reset the initial setting of the quartus prime.

5) did you install all the devices?

6) check if you have spaces in your directory names? If you had, try to replace the spaces with underscores.

7) Make sure all your folder are not in read only options.

Thanks

any update?
