MSI Package hangs-up when calculating disk space

Question

In my team we prepared an msi installer package for our application. Package is made in WIX contains custom UI, call custom actions from C# library and almost everything works fine except one thing: calculating required disk space. On this stage whole installer hangs up from time to time, especially when client testing it :( We have the same problems on developing machine, but restarting installer helps, so this error is quite random. I was googling a little bit and found two workarounds, all based on command line parameters:

msiexec /i filename.msi (change state messages handling)

and

msiexec /package /qr (starting package with limited UI)

unfortunately its not a solution for me, because installer has to working without passing extra parameters to it when user want to install application :(

I'll be appreciate for any clue in my investigation :)

It’s time to experiment

The exact cause is unknown but the workaround is to opt out of WiX's WaitForCostingDlg dialog.
