Updating an earlier version of Data Grip makes the 32 Bit version not working

Updating an earlier version of Data Grip makes the 32 Bit version not working

I have a DataGrip 2016.2.6 which if I update it find conflicts:

And produces an error log

Temp. directory: C:\Users\az\.DataGrip2017.1\system\tmp\patch-update

java.io.IOException: Cannot delete: C:\Program Files (x86)\JetBrains\DataGrip 2016.2.6\jre\jre\bin\server\classes.jsa

The original file cannot be launched for error:

---------------------------
Error launching DataGrip
---------------------------
The environment variable JAVA_HOME (with the value of C:\Java\jdk1.8.0_92) does not point to a valid JVM installation.
---------------------------
OK   
---------------------------

Which appears to be not true. There is a working jdk there.

Now, when I run the 64 Bit version of Data Grip it may work, and it wants to update itself which results in the above error - chasing its tail.

I appear to have been unable to upgrade Data Grip.
