"Packed Files Corrupt" Error When Installing |
The information in this document applies to:
WordPerfect® 5.1 for DOS
Problem
Solutions: A customer was get the error message "Packed Files Corrupt" when installing WordPerfect. He had Quarterdeck's QEMM with 7.5M of expanded memory. He was able to install WP after disabling the expanded memory or booting vanilla. Once installed, WP would only run without the expanded memory. The customer called Quarterdeck customer support and received the following information: "The EXEPACK program has a bug which makes it difficult to run a packed .EXE file in the first 64K of memory when the one-meg wrap (controlled by the A20 bit) is enabled. On some machines, when the A20 bit is enabled, a boot-up, and various .EXE files give the "Packed Files Corrupt" error message when run below 64K. QEMM 4.32, an earlier version, had a problem which actually helped the user to avoid this error message. This Problem was been fixed with QEMM 5, therefore the problem occurs more often. The U8 Parameter may help, but probably won't." In simpler terms, Quarterdeck is saying that the WP Install program comes with a packing/unpacking program that has a bug in it. This bug occurs when running Install if less than 64K of conventional memory has been used. Normally, over 64K would be used up by DOS, TSRs, device drivers, buffers, etc. However, when some of these items are loaded in high memory and you fall below 64K, you will likely get this error message when running Install under QEMM. This why the user was only able to install WordPerfect without QEMM. *This information is given strictly as a troubleshooting option. |
