 The icon file `silentdragon.ico` is currently not included in release zip, but is required to create an MSI installer with a smaller size. Setting icon SourceFile in the .wxs file to SilentDragonLite.exe will duplicate the .exe and make the installer over 100MB instead of ~80MB. How you get this .ico file is up to you. I extracted from .exe on Windows. Maybe it will be included in .zip release in the future to make this easier for anyone trying to create a MSI file for the first time. 
 
 ## Create WiX source file (.wxs)
 This is an XML file. You should name it what you want the .msi file to be named IE: `SilentDragonLite-1.5.2.wxs`
-Below is a copy of the contents of the `SilentDragonLite-1.5.2.wxs` file Note that GUID's all need to be unique. This will create shortcuts to SilentDragon on desktop and in the start menu as well as have uninstall support from Add/Remove Programs. A tutorial that explains the basics of creating these files can be found here: https://www.firegiant.com/wix/tutorial/

+## Potential known issue and work-around if wixl generates MSI with corrupt cabinet file
+There is a known issue where wixl may generate a corrupt cabinet file, causing the Windows installer to fail with a corrupt cabinet file error. This appears related to the file size of `SilentDragonLite.exe` and reported issue with gcab: https://gitlab.gnome.org/GNOME/gcab/-/issues/16
+
+File size where this becomes an issue is not exactly known, but it has occurred when `SilentDragonLite.exe` was ~100 MB. There is no cabinet file corruption when compressing `SilentDragonLite.exe` to ~80 MB. UPX is used to compress the executable and then MSI is created again: https://upx.github.io/
+
+### Install UPX ###
+```
+sudo apt-get install upx
+```
+### Compress SilentDragonLite.exe ###
+```
+upx SilentDragonLite.exe --force
+```
+### Re-create MSI using compressed exe ###
+```
+wixl -v SilentDragonLite-1.5.2.wxs
+```
