EPLAN Electric P8 2.9 SP1 (x64)
安裝完成激活后可以打開軟件，重啟電腦就出現 選擇許可 窗口，確定按鈕灰色的重新再次激活也是這樣。

卸載重新安裝軟件，又只能打開一次不能重啟電腦。

系統WIN10 X64專業版

1. Install the program

2. Open C:\Windows\System32\drivers\etc\hosts
Insert the following lines:
0.0.0.0 eplan.prod.sentinelcloud.com
0.0.0.0 licensingservice.epulse.cloud
0.0.0.0 licensingservice.eplan.com
127.0.0.1 eplan.prod.sentinelcloud.com
127.0.0.1 licensingservice.epulse.cloud
127.0.0.1 licensingservice.eplan.com
/or copy the finished one from the Crack folder/

3. Generate a license using Keygen\EPlanKeygen.exe:
Run EPlanKeygen.exe
Download TPL: select file - EPLAN_Electric_P8_Professional, or another, in the same folder as Keygen,
In the serial field, enter: WUP0UXXXXX (X is any combination of numbers), click Create.
EPlanKeygen CAM will generate and save the lservrc file in C:\Users\Public\EPLAN\Common

4. Open the generated lservrc, add 2 lines at the very beginning of the file:
"No Identity Check"
"Skip Identity Check"
(as it is). Save.
The item can be omitted if the following modules are installed in the Keygen configuration (see TPL):
Module_1450=Skip Identity Check
Module_30108=No Identity Check

5. Run EPlanPatcher, set all checkboxes
All necessary Dll-ki will be generated there - where it is necessary!

6. Everything..! Launch EPlan
p.s. run all programs as administrator

Tested on v2.6 (specially installed due to PPE), 2.9 and 2022 (2023 with a known issue).
All work "in parallel", i.e. simultaneously!
The function of copying between versions via the shared clipboard /Ctrl/+C, /Ctrl/+V also works.

激活過以后，過一段時間打開提示沒有license，一般就是沒有找到激活的tpl文件，只需要重新激活，不需要卸載重裝更不需要重轉系統     

2樓正解，感謝！
