UNARC.DLL RETURNED AN ERROR CODE 12 SOFTWARE

So running Error Checking on your disks might help.ĭoes your computer run fine otherwise? Is it fully updated? Have you scanned for malware? Replacing the battery is inexpensive, and easy with no harm done if not the problem.Ĭhecksum errors can occur when the hard disk is experiencing some corruption. This can be the result of some hardware change, or the BIOS/CMOS battery is failing. I often see RAM sticks test good and run good individually, but then fail when paired with other RAM.Ĭhecksum errors also occur when BIOS information at boot is different from when the last time the BIOS was saved. But these programs can report that RAM is good, but when put in use, they fail. That is, if they toss up even a single error, you can be sure the RAM is bad.

Note these software based testing programs tend to be really accurate when they report bad RAM.

Since the same installation appears to work on different computers, that suggests the original compressed installation file is okay, that something is happening during decompression, either with the decompression process, or with the saving of the files to disk.Īgain, because no software based RAM tester is 100% conclusive I still recommend running with 1 stick at a time. One or more of the uncompressed files is different than the same file before compression - hence the checksum error. I don't know what the problem is, but thinking out loud - Your description in your first post suggests (to me) there is a problem during the compression/decompression process with the installation package. I don't recommend that at all and if I were to encounter that situation, I would find another game to play, or different security. I note that several users have reported success installing and running misbehaving games by disabling their anti-malware scanners. But sadly, no software based memory checker is 100% conclusive so it may be necessary to remove all but one stick of RAM and see how that goes. I generally let MemTest run overnight so it can get several passes in. And finally, as seen here, it frequently does not resolve the problem! And that is common when the problem may be hardware related. Nothing is learned to prevent recurrence as evidence of the actual problem is destroyed. All your data and downloaded files will be lost - if not properly backed up. For one, it can set you months, if not years behind in security updates. Reinstalling the OS should ALWAYS be a last resort option for many reasons.
