my question: is there a tar-archive available? then installation would be easier.
thanks for any answers and hints.

No, there is no tar archive. You have to use the installer :-(
Is this the first time to attempt to install CPLEX on that box?
Did you check that the downloaded file was not corrupted (verify the checksum)?

fyi :
A potential root cause could be also the existence of a file named installer.properties with an escape character sequence.
The installer, automatically checks the directory in which it resides in for a file called installer.properties or installername.properties, and use it if it exists (If properties files with both of these names exist in the same directory as the client executable, the installer.properties file will take precedence.)
CPLEX Optimization Studio V12.4 doesn't generate the file, but we can not prevent the installer to use an existing file (generated by the V12.3 or also by another software).
So, you could check if a such file exists , and rename it , before launching a new installation.

A non-standard prompt can be also the root cause of this issue.
The workaround is then to redefine the PS1 variable :

export PS1=">"
