Challenges related to Patches ( lowercase letters in Product code )

[patchmaker]

Hello Community,

I have an App v1.0 that have a product code which containing numbers and lowercase letters such as {5ee1ba21-6526-4859-9c64-9ce2777c45ca}. When using AdvancedInstaller to create a Patch to update it to v1.1 I receive " ERROR: UpgradedImages.Upgraded = 'App': ProductCode is not a valid GUID" . It's due to that fact that product code contains lowercase and not uppercase letters. the App v1.0 is deployed into too many machines.

Is there any way trick to create a patch for updating to App v1.1 without the need to change the product code to uppercases for the v1.0 ?

Thank you for your support

Hello and welcome to our forums,

Your product code {5ee1ba21-6526-4859-9c64-9ce2777c45ca} is not a valid product code.

As per Microsoft GUID and Product Codes articles, a ProductCode is made up of string GUIDs containing numbers and uppercase letters.

You can also find more details about the ProductCode on our article here:
