Hi CCP4ers,

Need your help, many thanks.

When I was trying to install arp_warp_7.0.1.tar.gz in my CCP4i (6.0.windows version), it complained as " Failed to unpack and/or read contents of C:/CcprTemp/arp_warp_7.0.1.tar.gz. This may not be a valid CCP4i package.

Then, I unzipped this file, and found out a file named:ARP_wARP_CCP4I6.tar.gz.  Therefore, I instructed CCP4i to install this file, and it works! CCP4i said: Installation of "ARP_wARP_CCP4I6" completed successfully. Restart CCP4i to see the new tasks in the menu."

Everything sounds ok. I restarted pc, ccp4i, and tried to lauch Arp/warp. Then it complained again: Can not get environment variable for warpdoc!
