"The instruction at 0x00B2B4F1 referenced memory@0x0000001s. The memory could not be read. Click OK to terminate the program." Did search and a Community posting on Wiki suggested using Tech Utilities 2.0 to identify the solution and fix it. I backed up my registry and let it examine my computer. It showed 1131 errors throughout the registry, all being "Referenced filed doesn't exist" but I did not use its "Fix all issues" button. I regularly use Ccleaner for my files and registry. What is known about Tech Utilities? What alternatives do I have to cure the error? Suggestions appreciated.
