PA 12.01.03 failing to open 7z archive.

[AluminumHaste]

I just installed Powerarchiver 2011 Pro last night and it cannot open 7z archives that I’ve downloaded in the past few days.
When I try to open one of them PA throws an error:

“PowerArchiver cannot open this file. It does not appear to be a valid archive”

So I downloaded the 7z file manager and it has no problems opening the same files.
Strangely enough however, I used PA to create a 7z archive and PA has no problems opening that file.
Here is the link to one of the files that is failing:

Hello!
The attached link links to a forum where I do see some 7z files attached, I’m assuming some of those files are what you are referring to?
I’ve downloaded and tested
Vurt’s SS2 Flora Overhaul v01.7z

I’ve tried to open/extract them with PA 2011 and it worked fine. Can you point me to a specific 7z file that doesn’t work for you?
I’ll give it a try with that one.

Thanks!

Vurt’s SS2 Flora Overhaul v02 fails to open for me, try that one. I’ll try the v01 file.

EDIT: The file Vurt’s SS2 Flora Overhaul v01.7z does open just fine with PowerArchiver. Perhaps his 7z files are corrupted somehow.

Yep, same here.

I’ll log this one in and see what the dev team has to say. Looks like its something specific.

Thanks for reporting it!

Not a problem, thank you for looking into it, as I said the 7z File manager has no problems opening these files.

what version of 7z are you using? Our dll is latest official one, there “shouldnt” be any issues.

[AluminumHaste]

According to 7zip I’m using 7z 9.20 which I see is the same version of the DLL in my PowerArchiver directory

[AluminumHaste]

I just tried the beta 9.22 DLL 7z file but PA has the same problem with some of those files.

it is something weird, we will figure it out

[AluminumHaste]

No problem, take your time

[spwolf]

it is rar archive, not 7z… rename extension to rar and it will work fine

[AluminumHaste]

Ah that explains it. That is a little strange as PA is usually pretty damn good at figuring out the actual format of the file regardless of it’s extension.

we will see what we can do about detection in this case…
