Hi, everyone ** including more information **
I have question on maintaining uninstall version compatibility.
In order to make new msi build able to uninstall the previous version I
assigned fixed guid to
Id attribute in my package tag; looks like below:
<Product UpgradeCode="F3485790-281D-400C-A76C-C12B5AD7EE50" Name="W Service"
Id="E7DB0CC6-0423-4B73-90BB-473406592C01" Version="1.0.0"
Manufacturer="Corporation Experience" Language="1033">
<Package Id="516E8548-CA5D-431F-80FC-4CFDD8999ED5"
Manufacturer="Corporation Experience" InstallerVersion="200"
Languages="1033" Compressed="yes" SummaryCodepage="1252" />
<Upgrade Id="F3485790-281D-400C-A76C-C12B5AD7EE50" >
<UpgradeVersion Minimum="1.0.0" Property="NEWERPRODUCTFOUND"
OnlyDetect="yes" IncludeMinimum="yes" />
</Upgrade>
<Media Id="1" EmbedCab="yes" Cabinet="_1DB1A4518738299294125E0171CEB0DB"
/>
The problem is above generates warning during compilation, is there anyway
to eliminate the
warning during compile? Is there better way to ensure compatibility?
Here is what my warning message look like:
c:\enlistments\source\services.install\product.wxs(36) : warning CNDL1091:
The Package/@Id attribute has
been set. Setting this attribute will allow nonidentical .msi files to
have the same package code. This may be a prob
lem because the package code is the primary identifier used by the installer
to search for and validate the correct pack
age for a given installation. If a package is changed without changing the
package code, the installer may not use the
newer package if both are still accessible to the installer. Please remove
the Id attribute in order to automatically g
enerate a new package code for each new .msi file.
Thank you.
