Danielle Posts: 1275 Rating: (123)	Hi V, Yesterday I talked to that guy with the problem. I had asked him to make sure his Windows Firewall had been disabled, but he told me somehow he couldn't access Windows firewall's configuration. Apparently something's wrong with his Windows, which is keeping the firewall enabled and not letting him access the settings. The IT people here have never seen anything like this before... he has all the right privileges.well.. now they just gotta figure out how to change the firewall settings, or he'll have to format his computer.. [:P] How about you? Any news? Best regards, Danielle

Danielle Posts: 1275 Rating: (123)	Hi V, I checked on that situation again, and the guy got to disable windows firewall (don't ask me about that windows firewll issue [:o]) and it still hasn't worked. [:(] There's more thana few Siemens software in his computer. However, Step7, WinCC and Windows are compatible. He's not sure about when he installed Pro Tool. Could that be the problem? I'm not sure if Pro Tool shares files with WinCC... He also has Drive Monitor, WinSimocode, MicroWin and some other software, which I believe wouldn't have impact on WinCC. He's never installed WinCC Flexible, though.He can't tell when this problem started 'cause he hasn't used WinCC in a long time. There's quite a Siemens software park in that notebook, and he wouldn't like to have a drive image just for WinCC. Does anyone have any ideas? Oh... he has McAffee anti virus, but I have the exact same here, with no problems... could having McAffeeduring the software installation be the problem? If that was the case, then WinCC wouldn't have worked to begin with... [:(] Best regards, Danielle

Cant' say I have any news at the moment, support went quiet after their first answer on my request!!!!![:mad:] I had protool installed on my eng.station prior to installing WinnCC flexible and had no problems then, and was running this for months. So I don't think protool is causing the problems. . The problems did appear on the first start of WinCC HMI after installing WinCC flexible. I'm setting up a PC for testing of this now, will try different installation combinations to try to find the cause of my problem without disturbing the eng.station which I'm using daily. Will let you know when I know if or when I find anything. V

Big Bear Posts: 27 Rating: (2)	You must install your software in this order: Step7 Protool (any possible protool updates) WinCC - Flexible (any possible flexible updates) WinCC (any possible updates) This "should" get you up and running. I think your issue is newer files as others have pointed out, so this order is the only way you can ensure you are using the latest files. Now, doing this should enable WinCC to function normally, but I have no idea how it will affect protool or flexible. Good luck!

Danielle Posts: 1275 Rating: (123)	Flexible usually works fineif installed before WinCC. At least it always did when I had it! [:)]However, in my co-worker's case, Step7 was installed before WinCC, and WinCC Flexible was never installed. [:(]

Danielle Posts: 1275 Rating: (123)	Hi V, I finally have some good news: my co-worker's case has been solved. Here's the thing: some software, I can't tell which, disabled DCOM on his computer. To access that he ran dcomcnfg.exe. My Wincowds is in portuguese, so some of the following names may be inaccurate. On Component Services under Component Services -> Computers right-click the option "My Computer" and select "Properties". On a tab which in portuguese is called "standard properties" you need to check the option "Activate DCOM on this computer". That box had been un-checked somehow, probably when he installed something else. He also got a reply from Siemens germany, by mail, with instructions to rectify this error. He hasn't read this e-mail from Siemens, 'cause his problem got solved just before he got it. I asked him to forward this e-mail to me, and I'll tell you what it says as soon as I get it. It may help you, if your problem isn't related to that checkbox. Best regards, Danielle

vidarv Posts: 66 Rating: (1)	Hia Danielle! Thank you very much for your efforts [:D] I have now installed in this software on my station Step 7 WinCC HMI Simatic Net Drive ES Protool WinCC Flexible I did install in the order as shown above, I know this is not how you said I should, but I wanted to test a the same installation procedure as on my initial installation. The only difference is that I on the first installation upgraded to SP4 and HF2 for WinCC HMI prior to installation of WinCC flexible, this time I installed SP4 HF2 for WinCC HMI directly. I have now tested S7, protool, WinCC HMI and WinCC flexible, everything is working !![:D] Difficult to conclude, but MAYBE the upgrade of WinCC to SP4 HF2 was the problem!? Anyway, thanks everyone!! PS, Danielle I am still interested in the reply you got from support germay, would be nice if you could post it here ? Cheers V

Danielle Posts: 1275 Rating: (123)	Hi V, Here's what support sent us, they're working with the possibility of pcAnywhere disabling DCOM. That's not what happened in our case, since pcAnywhere had never been installed. Still, here it is, in case it may help you: Please check the following FAQ: >>http://support.automation.siemens.com/WW/view/en/16640039 The FAQ descibres the software pcAnywhere which disables the DCOM Interface. There are other software packages that disable the DCOM Interface aswell. Restart the PC, download the *.reg file and execute it. After this step WinCC should work again. Best regards, Danielle

vidarv Posts: 66 Rating: (1)	Hia again! I find this PCanywhere issue as a interesting point, I had PCanywhere installed on the engineering station. I did at some point uninstall it and it is possible that I didn't use WinCC in the time between uninstalling PCanywhere and installing WinCC flexible. It could very well be that my problems was not caused by WinCC flexible installation, but uninstalling PCanywhere!? Anyway, my ES is now working perfectly, after again having doubts about WinCC I'm again a happy user![:D] Thank you all again for making this forum a great place to seek advice and help. Cheers V

Danielle Posts: 1275 Rating: (123)	From what I gather on installing PCAnywhere DCOM would be disabled. We actually have an engineering station on a customer's site which has PCAnywhere, but no-one mentioned running into this problem. Did you run WinCC successfully while you had PCAnywhere? In theory the problem should've began as soon as PCAnywhere was installed, right? It's always nice to see another WinCC user happy! [:)] Best regards, Danielle
