I assume you are trying to use IDSA to update your graphics driver.
What operating system? WIndows 10? What version? 1909? 1903 (with all updates)?
What is your processor model number?
What is your laptop or motherboard model number?
You should use ONLY the drivers from ACER, especially if you have DUAL graphics.
Now, if you really want to install the latest Intel generic DCH driver, do this.
Now, using the Intel DCH driver instead of the ACER supplied driver, you will lose any customizations/modifications Acer has done. This may be ok for you. BUT... If you have Dual graphics (nvidia or amd), you may cause yourself problems with the switching between the graphics.
Also, the next time you run IDSA, it should work for you.
