Windows 7 ACPI Compliant Error (0x000000A5)


We need to install Windows 7 on a computer with a Dell Optiplex 5070 model.
We get the following error on the installation screen.
Can I find a modified .ISO for this bug?

@2run Welcome to the Win-RAID Forum!

You will not find a modified Windows ISO file here. We don’t want to get copyright lawsuit problems with Microsoft. If you need to get Win7 installed onto a modern PC, you should do the required actions yourself.
Good luck!

Thanks for information.
Is there a topic where I can get information on how to do this?

Please use the Forum "Search" option by entering "ACPI Win7".

I searched on the forum but couldn’t find any results.
How can I get exactly the acpi.sys file I need? Any chance of linking?

You cannot expect within this Forum any help, when you are searching for a driver, whose hex code has been modified.

Try fix from here, it’s just a simple HxD change.…&comment=137330

Hello. Where I can download last version acpi.sys from Windows 7 for Ryzen 5 2600? I don’t know how use HEX redactor and fix standard acpi.sys. I downloaded acpi.sys 2018, and computer become best working, but not ideal.

I cannot help you, because I don’t modify any *.sys file.

Thanks. But who change files *.sys? Where uploaded this files? I random find acpi.sys 2018 on IXBT forum, but this is not latest version.
