I was installing PowerChute Business Edition version 9.0.1 on SMT1500, SMT1500I and SUA1500GB.The first installation worked fine. The computer was finding automatically the UPSs via USB connection and I could configure them without any problem. Every time I changed a unit I had to re-install the software on my computer. When I had to install PowerChute second time it could not find SMT1500I but worked OK with two other units. I noticed that at the second installation the SMT1500I unit uses https://localhost:6547 for USB connection while originally it used http://localhost:3052 . When I installed PowerChute on a different computer it worked fine with the same SMT1500I unit connecting to it via https://localhost:6547. Any idea what could be the problem?
