Hi,
As part of major upgrade, I would like to copy one file from the previous
version installed to some location. I want to do this only when a previous
version of the product is installed. I don't want to do this CopyFile when this
is a fresh installation.
Here is what I am trying :
Do a component search and get the full path of the file. Inside a component put
a CopyFile element like:
<Property Id="OLDFILE" Secure="yes">
<ComponentSearch Id="OldFileComponentSearch" Guid="{Guid1}"
Type="file" />
</Property>
<SetProperty Id="OLDFILEFULLNAME"
Value="[OLDFILE]abc.xml" After="AppSearch"/>
<Component Id="MoveOldFile" Guid="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
KeyPath="yes">
<Condition>![CDATA[OLDFILE]]</Condition>
<CopyFile Id="CopyoldFile" DestinationDirectory="myDir"
DestinationName="NewFile.xml"/>
</Component>
When the older version of the product is installed on the machine then this
code actually copied the old file as expected.
But when there is no older version installed, this is still trying to do
CopyFile and failing. I have tried to set the condition to 0 and even
then CopyFile is executed. Doesn't the condition apply for the CopyFile
element? - It looks like this to me.
I tried one more thing as well. I put a File element inside the component
element and inside that put the CopyFile element something like:
<Component Id=" MoveOldFile " Guid="xxxxxxxxxxxxxxxxxxxxxxxxxxxx" KeyPath="yes">
<Condition><![CDATA[OLDFILE]]></Condition>
<File Id="SomeDummyId" Source="SomeDummyFile.xml">
<CopyFile Id=" CopyoldFile " DestinationDirectorymyDir"
DestinationName="NewFile.xml"/>
</File>
</Component>
Now, everything works expected. The copyfile is not executed if the condition
is false but I cannot copy some other file than the file which is installed by
this component. (I cannot set the PropertySource attribute of CopyFile if the
CopyFile is nested under File element).
Is there some way that I can tackle this problem?
Thanks
Ram
