Exception trying to unpack nested CAB

[pol098]

Error running TCMD 9.0RC6 32-bit in administrator mode under Win10/64. I opened file HPUSBFormatter.exe (an SFX) as an archive, which displayed as several files including one named data1.cab. I then keyed Ctrl-PgDn to open this nested CAB, and got an error window, copied below. On continuing I then got a TCMD error window: "7-zip library is not found. Download 7-Zip", followed by "error in packed file". However, if I extract data1.cab and try to open it with 7-Zip (not from within TCMD) it is reported as not being an archive. [The file HPUSBFormatter.exe itself I extracted from a file I have renamed as "HP USB Disk Storage Format Tool_218_installer.exe"; I don't remember the original name, perhaps "HP USB Disk Storage Format Tool.exe".]

Clevo computer, Intel CPU, Win10/64, up-to-date.

I report this for information as it raised an exception rather than just an error message; it is not a problem for me, and may not be worth looking at.

I don't seem to be able to attach a file, but can supply it if required.

Further checking: the exception is repeatable with 32-bit TCMD in admin mode, but does not occur in 64-bit, non-admin mode, and does not occur with Ctrl-PgDn on the extracted data1.cab. There is an error message about the 7-Zip library in those cases.

Unfortunately the error address isn't in Total Commander. The last code in the stack trace which is part of Total Commander is a call to PeekMessage, which is called in a callback from the CAB extractor dll.

Furthermore, I could not reproduce your problem: I found the mentioned file and looked inside, but only get an unpack error from the CAB files inside because they are not Windows CAB files - they are InstallShield CAB files which cannot be unpacked by TC.

So the problem isn't related to unpacking CAB files, it must be some third party window (e.g. from a plugin) executing bad code when TC handles Windows messages.

I also couldn't reproduce the problem. I tried with TC 9.0 RC6 32-bit, with clean INI:
- under Windows 7 with TC launched as administrator,
- under Windows 2000.

MD5 of HPUSBFormatter.exe that I tried is: ae2bd23e0a380ca770a2b542b5125228.

That is the same as the MD5 of the file I have been using. So not a TCMD problem at all. I'm not going to proceed further, as it's not a problem to me anyway.
