While extracting: Value of '893' is not valid for 'Value'

[colemar]

Describe the bug
A clear and concise description of what the bug is.

Value of '893' is not valid for 'Value'. 'Value' should be between 'minimum' and 'maximum'.
Parameter name: Value

Technical Detail:

   at System.Windows.Forms.ProgressBar.set_Value(Int32 value)
   at LessMsi.Gui.ExtractionProgressDialog.UpdateProgress(ExtractionProgress progress)
   at LessMsi.Gui.ExtractionProgressDialog.UpdateProgress(IAsyncResult result)
   at LessMsi.Msi.Wixtracts.ExtractionProgress.ReportProgress(ExtractionActivity activity, String currentFileName, Int32 filesExtractedSoFar)
   at LessMsi.Msi.Wixtracts.ExtractFiles(Path msi, String outputDir, MsiFile[] filesToExtract, AsyncCallback progressCallback)
   at LessMsi.Gui.MainForm.btnExtract_Click(Object sender, EventArgs e)

To Reproduce
Steps to reproduce the behavior:

1. Open TopazVideoAI.msi
2. Click on [Extract]
3. At about 100% progress see error above

Desktop (please complete the following information):

• OS: Windows 10

Additional context
lessmsi.exe x TopazVideoAI.msi MSIEX\ works well, but last line shown is 894/892 Topaz Video AI.exe.

Hello @colemar.

I'd like to work on this issue and will be grateful if you can provide the msi file you used.

Thank you.

Sorry, I don't have the msi file anymore.

I see.
In a quick Google search, I found the next link for TopazVideoAI.msi:
https://docs.topazlabs.com/video-ai/download-and-install

Let me download it and check if I am able to reproduce the issue you have.

@mega5800 I bet it is possible that if there are files with the same name (which we know occurs for installers supporting x86 and x64) it could end up sending a file count during progress multiple times which could exceed the maximum value. This could occur due to the simplistic check at

lessmsi/src/LessMsi.Core/Msi/Wixtracts.cs

Line 330 in 68cde3e

if (!fileEntryMap.ContainsKey(compressedFile.Filename))

You could probably create a unit test on an msi that has two files with the same name, but two different platforms and do an extraction and get it to call progress.ReportProgress with a value that is greater than the TotalFileCount value it was initialized with.

One way to fix might be to make sure that the ExtractionProgress class updates the _totalFileCount on every updateProgress call just before it updates the _filesExtractedSoFar value at

lessmsi/src/LessMsi.Core/Msi/Wixtracts.cs

Line 73 in 68cde3e

_filesExtracted = filesExtractedSoFar;

It might be a little weird that the TotalFiles value might change over time, but seems reasonable.

Just an idea. Hope this helps!
