Halt on Extract


Ascii2

Recommended Posts

I am using Universal Extractor 1.6 beta with the current innounp pnpacker.

When attempting to extract some installers of Inno Setup type with Universal Extractor, the process halts and prompts:

Type in a password (empty string to quit)

How can Universal Extractor be made to finish the extraction?

A similar thread from another forum is similar to this one:

If the installer can continue its installation without prompting the user for a password, it should use the password itself during runtime. If the password is used during runtime it should be able to be captured.

I remember from a thread I read (although I do not remember where) that Inno Setup compares hashes, and the installer's hash or hash comparison can be modified to allow extraction to complete. I did not know how to actually accomplish such a thing.

I found the thread that seems to have found a way around the pssword protection (although I am still uncertain if it applies to installers that do not prompt for password during normal install process). The thread may be found:

What should be done to get around the password?

Ascii2, as the other forum members have noted, Inno Setup provides the ability to encrypt installers using the optional encryption module found here:

http://www.innosetup.com/isdl.php#crypt

In order to decrypt the installer (necessary for extraction), the proper password must be specified. By default, as you've obviously noticed, innounp can't support encrypted installers.

However, the post that you linked to looks like it may provide a way to work around it. I'd be interested in investigating it for the next version of UniExtract. I recommend adding your suggestion to the feature request thread to make sure I don't forget about it.

newest innouno 0.23 is working nice, you probably not put in same folder (bin in case of UniExt) new folder with language dll's (for english example: \bin\Lang\1033.dll) which come with innounp.exe
