Deployment Add operation with target volume C: on Package
MicrosoftHi Amit Kumar,
Looking at the error message you have shared, it appears to be in-relation to the certificate used to sign your Windows App (*.msix). The certificate may not be trusted by the device, the certificate may have expired, or it and/or its parent certificate have been revoked (see the Certificate Revocation List).
Please check the status of your code signing certificate used to sign the Windows App.
Thank you,
Roy MacLachlan
I am having the same issue here. Bought the HEVC codec from MS and boom:
App installation failed with error message: Deployment Add operation with target volume C: on Package Microsoft.HEVCVideoExtensions_1.0.50362.0_x86__8wekyb3d8bbwe from: (Microsoft.HEVCVideoExtensions_1.0.50362.appx) failed with error 0x80073CF3. See http://go.microsoft.com/fwlink/?LinkId=235160 for help diagnosing app deployment issues. (0x80073cf3)
Please incorporate this codec in windows?
joostreedijkcom I also got the same error.
Initially we had our app build on xamarin with appxbundle extension. then we build same app in MAUI now the extension is .msix. Both uses the same name and certifcate. when i try to update xamarin version app with MAUI. I also got the same error .0x80073CF3.
App installation failed with error message: Deployment Add operation with target volume C: on Package ********** from: (******.msix) failed with error 0x80073CF3. See http://go.microsoft.com/fwlink/?LinkId=235160 for help diagnosing app deployment issues. (0x80073cf3)
Please share if any one have any solutions.
rethishannathanks for the information... same issue, but the internet was assuring me it was a certificate error. Bundling the installer with makeappx (*.msix > *.msixbundle) thankfully resolved it. It appears msixbundle can upgrade an appxbundle, and msix an appx, but the two categories of installer can't mingle.
