Hello, our software is compiled with C++, Visual Studio 2017 and therefore we have provide the Microsoft Visual C++ Redistributable for Visual Studio 2017 with the installer as a prerequisite. Unfortunately, the installation fails because a newer version is already installed. How do you deal with this problem? This seems to me like a problem everyone has to face using redistributables. The log output from the redistributable is: [CODE] [2818:12FC][2018-08-03T12:56:19]i001: Burn v3.7.3813.0, Windows v10.0 (Build 17134: Service Pack 0), path: c:\Program Files (x86)\InstallShield\2018\SetupPrerequisites\VC 2017 Redist\vc_redist.x64.exe, cmdline: '' [2818:12FC][2018-08-03T12:56:19]i000: Setting string variable 'WixBundleLog' to value 'C:\Users\Michael\AppData\Local\Temp\dd_vcredist_amd64_20180803125619.log' [2818:12FC][2018-08-03T12:56:19]i000: Setting string variable 'WixBundleOriginalSource' to value 'c:\Program Files (x86)\InstallShield\2018\SetupPrerequisites\VC 2017 Redist\vc_redist.x64.exe' [2818:12FC][2018-08-03T12:56:19]i000: Setting string variable 'WixBundleOriginalSourceFolder' to value 'c:\Program Files (x86)\InstallShield\2018\SetupPrerequisites\VC 2017 Redist\' [2818:12FC][2018-08-03T12:56:19]i000: Setting string variable 'WixBundleName' to value 'Microsoft Visual C++ 2017 Redistributable (x64) - 14.10.25017' [2818:12FC][2018-08-03T12:56:19]i100: Detect begin, 10 packages [2818:12FC][2018-08-03T12:56:19]i000: Setting version variable 'windows_uCRT_DetectKey' to value '10.0.17134.165' [2818:12FC][2018-08-03T12:56:19]i000: Setting numeric variable 'windows_uCRT_DetectKeyExists' to value 1 [2818:12FC][2018-08-03T12:56:19]i107: Detected forward compatible bundle: {5b295ba9-ef89-4aeb-8acc-b61adb0b9b5f}, type: Upgrade, scope: PerMachine, version: 14.14.26405.0, enabled: No [2818:12FC][2018-08-03T12:56:19]i102: Detected related bundle: {5b295ba9-ef89-4aeb-8acc-b61adb0b9b5f}, type: Upgrade, scope: PerMachine, version: 14.14.26405.0, operation: Downgrade [2818:12FC][2018-08-03T12:56:19]i108: Detected compatible package: vcRuntimeMinimum_x64, provider: Microsoft.VS.VC_RuntimeMinimumVSU_amd64,v14, installed: {BCA8F863-9BAB-3398-B8E4-E1D0959D0943}, version: 14.14.26405, chained: {8D4F7A6D-6B81-3DC8-9C21-6008E4866727} [2818:12FC][2018-08-03T12:56:19]i103: Detected related package: {BCA8F863-9BAB-3398-B8E4-E1D0959D0943}, scope: PerMachine, version: 14.14.26405.0, language: 0 operation: Downgrade [2818:12FC][2018-08-03T12:56:19]i108: Detected compatible package: vcRuntimeAdditional_x64, provider: Microsoft.VS.VC_RuntimeAdditionalVSU_amd64,v14, installed: {A2999714-5C2C-3729-A911-4AE198B7B2FD}, version: 14.14.26405, chained: {E512788E-C50B-3858-A4B9-73AD5F3F9E93} [2818:12FC][2018-08-03T12:56:19]i103: Detected related package: {A2999714-5C2C-3729-A911-4AE198B7B2FD}, scope: PerMachine, version: 14.14.26405.0, language: 0 operation: Downgrade [2818:12FC][2018-08-03T12:56:19]i052: Condition '(VersionNT = v6.3 AND NOT VersionNT64) AND (windows_uCRT_DetectKeyExists AND windows_uCRT_DetectKey >= v10.0.10240.0)' evaluates to false.
