It's time to update TC7Z.DLL and TC7Z64.DLL ||And Win9x fix?

[MaxX]

After all.... The only way to have up-to-date 7Zip DLLs without losing Win9X compatibility is "TC7Z9x.dll" for older vesion (9.20 works fine there), just the same as "UnRAR9x.dll".

TC7Z9x.dll ... same as UnRAR9x.dll

Sounds like the ideal solution to me

I'm considering to go back to the old 7zip dlls because the new are faulty also in other ways. for example, download this 7zip archive:
https://notepad-plus-plus.org/repository/7.x/7.1/npp.7.1.bin.7z

1. Unpack to empty directory
2. Run notepad++.exe
3. Try to unpack again -> TC hangs when trying to overwrite SciLexer.dll (but not when trying to overwrite notepad++.exe)!

Not confirmed under TC 9.0 RC2 x64 in Windows 10
I have no problems to unpack all files again.
May be the DLL was not unloaded in your case ?

No, it happens only while notepad++.exe is actually running! Trying to overwrite notepad++.exe will result in an error message, but trying to overwrite SciLexer.dll will make both TC 32-bit and TC 64-bit hang forever.

Does standalone 7Zip hang in this case?
May be, file is blocked by some AV-services (or is in use by something)?

Total7zip plugin has no problems with this scenario.
It just complains about a few open files and you can go on.
Also the 7-zip file manager has no problems it just lists the files with access problems and extracts the rest.

I found out what the problem is: the dll sometimes calls back to TC from a backgroud thread. Since Delphi forms are not thread safe, I use SendMessage to activate the main thread - but it is blocked waiting for the 7zip operation to finish. Moving the 7zip operation itself to a background thread fixed this.

Furthermore, I have now compiled the 7zip dll 16.4.0.0 myself with Visual C++ 6.0, so it works on Windows 9x/ME too now.

Great! That's the best news for today!

Excellent work!

Perhaps also compile similarly the LZMA library 32+64 DLLs to the latest 16.04 ?

i got some problems with 7zip 16.04:
with TC 32 bit you don't get the following information in the zipfile if you click in the file:
name, date, attribute

next problem:
If you use Alt-F9 to unzip the container you get an empty folder.
unzip via context-menue does work.

with TC 64 bit everything works.

I do not have these problems, 7zip files show the details just fine and unpack without problems. Maybe it's someincompatible format? Where can I find a 7zip file with this problem?
