Hi there,

I have convert InstallScript project type into Basic MSI project type and build UWP app by using repackager in AdminStudio and Permier edtion InstallShield 2018.
I would like to sign the UWP app package with my own digital certificate, so I do the following steps:

1. select my .pfx file path in "Digital Certificate Information", Digest Selection: Based on certificate hash.
2. fill in the certificate password in "Certificate Password".
3. select Windows Installer Package in "Sign Output Files".

And there is an error message shown:
SigningHelper: error 0x800700c1 while attempting to sign file.
ISDEV : error -1027: Failed to sign UWP app package.

Is there any way to sign UWP application successfully?
Thanks.

Best regards,
