I'd recommend you post questions in English language. This will increase the chance it will be answered sooner.
Anyway, below is translation of your question:
"I encountered some problems when installing S32DS v3.4 and RTM4.0.3, as shown in the attachment, an error was reported, I don't know why, when I installed it on other computers before, this problem did not occur, I hope it can be answered"
From the screenshot I cannot identify RTM package or which device you are you are trying to install.
Anyway as a general suggestion I'd first install the generic packages such as "S32 Design Studio platform" and "S32 Design Studio tools platform", debugger/PEMCO packages/updates and then restart S32DS and proceed to Development packages for the device you are using. Finally, I'd install the SDK package dedicated to your device family or specific device.
FYI: there is newer version of S32DS v3.5 (update 13) already available so if you are starting your project development it could be better to switch to latest version.
Sorry for the late response. My previous project was created using S32DS 3.4 based on the S32_SDK_S32K1xx_RTM_4.0.3 extension package. After downloading S32DS 3.5, I am unable to open the project correctly. When I try to download S32DS 3.4 on a new computer, I get an error message. Could you please help me resolve this issue?
I'd suggest NOT to mix workspaces for different versions of S32 Design Studio.
The default workspace folder name includes the version of S32DS in its name.
Trying to open workspace created in v3.4 in 3.5 and vice versa might generate some errors.
If you intend to use your existing project created in S32DS 3.4 + SDK 4.0.3 I'd suggest you use the original S32DS version and same SDK version.
First install both S32DS + SDK + S32K1xx development package and then import/open the project.
The updater errors seem to be related to a non-available update site.
Are you able to proceed to project build even with the errors you posted?
BTW: what kind of error you get when you imported and build the original project in S32DS v3.5?

>> I didn't try to build,. In fact, I usually build the project by IAR EW ARM.
BTW: what kind of error you get when you imported and build the original project in S32DS v3.5?
>> It will show me like "doesn't support RTM 4.0.3" when I import the original project, and I can't open like Driver, PIN, Clock and modify any configuration file.
BTW: if there is no way to instill, Is there any way for me to copy S32DS and RTM4.0.3 in my old computer?
