I hope this helps.
From the postintall.sh it appears that it is failing while writing to temp dir.
Error:
Failed to set first configuration value. Failed to execute 'chmod 777 "C:\Program Files\IBM\snapvault/tmp"'
Try this:
From the command prompt enter 'set' to see your current environmental variables.
Step 1:
C:\Users\Administrator>set
ALLUSERSPROFILE=C:\ProgramData
APPDATA=C:\Users\Administrator\AppData\Roaming
CommonProgramFiles=C:\Program Files\Common Files
CommonProgramFiles(x86)=C:\Program Files (x86)\Common Files
CommonProgramW6432=C:\Program Files\Common Files
COMPUTERNAME=WIN2K8R2
TEMP=C:\Users\ADMINI~1\AppData\Local\Temp
TMP=C:\Users\ADMINI~1\AppData\Local\Temp
Step 2:
In the output, locate
TEMP=
TMP=
Change these values to 'C:\temp' and then create the directory if it does not exists.
C:\Users\Administrator>set TEMP=C:\temp
C:\Users\Administrator>set TMP=C:\temp
Run the installation again check if it succeeds. If it fails, change the values back to original.
