Hello Lalit I'm afraid you'll need to get a Step7 V5.4 license (or upgrade yours to a V5.4 license) to run any of the V5.4 versions (no SP, SP1, 2 ,3 ,4 or 5). |

Hello again Lalit unfortunately YES (I know its painful and takes time but you can NOT simply "downgrade" an installation). Have a look at this link too which helps in ensuring that you do a real "clean" uninstall: How can you completely uninstall STEP 7 including all the software packages |

Ican appreciate how lalit ended up in the situation that he/she ended up in. The golden rule is quite simple: Every version number change (e.g. V5.3 to V5.4) is an "upgrade" and requires a new license. Every Service Pack (SP) or Hotfix (HF) within that version number(e.g. V5.4 to SP1toSP2 to SP 3 to SP 4 to SP 5) does NOT require a new license and is provided free of charge. Lalit, if you want to ensure to keep your Step7 always up to date you may want to consider purchasing a so called Software update service (SUS). You seem to be a regular user and may find that this will be cost beneficial for you (or your company),speak to your local Siemens rep to fidn out more about pricing and advantages. |
