AdvancedInstaller@2 is failing with Advanced Installer Tool Installer extension v2.0.2

[marwa.elghali]

Hello,

Our Azure DevOps build pipelines utilize the task AdvancedInstaller@2.

As of today, all such pipelines are failing at this step with the below error message, even though we have not applied any changes on our side, and the pipelines were successful as of this morning.

##[error]Cannot read property 'ProductVersion' of undefined

I can see that the Advanced Installer Tool Installer extension we have in our pipelines has been updated yesterday to version 2.0.2.

For installation of Advanced Installer within the pipeline, we use the task AdvancedInstallerTool@1, without specifying any version, so it is retrieving the latest version (v 23.5.1 x86) and it is cached within our build agents.

The inputs to the AdvancedInstaller@2 task are:
aipPath: <path to our .aip file>
aipResetDigSign: true
aipExtraCommands: |
SetOutputLocation -buildname "SystemMode" -path "<path to build>"
SetOutputLocation -buildname "UserMode" -path "<path to build>"
SetVersion <semantic version of build>
SetProperty ARPCOMMENTS="<copyright text> Version:<build version>"
SetProductCode -langid 2057 -guid <product code>

Appreciate any assistance.

Issue seems to have gotten resolved on its own today.

Hello Marwa, Anthony,

I'm sorry to hear that it still hasn't worked.

Cna any of you share with me the following, by email at support at advancedinstaller dot com:

- a copy of the AIP file

- a copy of the build log

- a copy of the YAML file (only the part that involves Advanced Installer)

so I can further investigate this on our end?

We have tried to run some tests but were not able to reproduce the issue on our end, so most likely you have something configured differently on your end.

Best regards,
Catalin

Hi,

We are experiencing the same issue, also with version 2.02 of the AdvancedInstaller Tool.

This is the part of the yml we are using:

Code: Select all

- task: AdvancedInstaller@2
    displayName: 'Build Advanced Installer package Codex Installer.aip'
    inputs:
      aipPath: 'E:\installer\Codex Installer.aip'
      aipBuild: Build
      aipExtraCommands: |
        SetVersion $(AssemblyInfo.ProductVersion)
        SetAzureKeyVaultSecret $(SigningClientSecret)  

This is the error:

Starting: Build Advanced Installer package Codex Installer.aip

Hopefully this will be fixed soon.

Hello Gernant and welcome to our forums,

If possible, could you please also provide the build log? You can send it via email at support at advancedinstaller dot com.

We have tried multiple tests on our end but we are unfortunately not able to reproduce this.

The only thing I can think of is to double check the following variable: $(AssemblyInfo.ProductVersion) has a valid version that is compatible with the MSI standards (ProductVersion property).

Best regards,
Catalin

Hi,

I don't think the problem lies in the Product Version parameter we pass to AdvancedInstaller, but in the AdvancedInstaller tool trying to find (or parse) the product version on https://www.advancedinstaller.com/downloads/updates.ini
The product version we are passing is: 6.7.0.0 and was working before the pipelines started to fail (as from Tuesday March 17th).

Here's the relevant piece of the build log, included is the step that retrieves the (our) product code from an assembly:
