Thank you for you answer.
I have downloaded the Delisoft.DSLocalizator.DNN3.01.00.23-PA file again this morning. When I try to install the module on DNN 04.05.03, I have the following error :
ExceptionICSharpCode.SharpZipLib.ZipException: Wrong Local header signature: 0x34B5082 à ICSharpCode.SharpZipLib.Zip.ZipInputStream.GetNextEntry() à DotNetNuke.Modules.Admin.ResourceInstaller.PaInstaller.ReadZipStream() à DotNetNuke.Modules.Admin.ResourceInstaller.PaInstaller.Install()
I also tried to uncompress the file with winrar and 7zip. With both I had an error saying that the file was corrupted.
With the Delisoft.DSLocalizator.DNN3.01.00.07-PA file I don't have these issues. I can uncompress or install the module, but it seems that it doesn't work well with my DNN version as I didn't manage to install the hack.
Would you have any idea of what could the problem be?
