error message appears after opening a pdf file with Acrobat Reader DC

Question

I uninstalled Acrobat Reader DC several times, even used the cleaner tool to uninstall and re-installed. I still get the same error and cannot open documents or use the program.

"The instruction at 0x5fa6525c referenced memory at 0x00000000. The memory could not be read.

Click on OK to terminate the program"

any help from Adobe experts will be greatly appreciated. Thanks
