Thank you for Mr.Steve and the answer.
Because "DBSM cannot be installed" problem was solved, we will report.
It easily explains the situation.
When DBSM is installed with other MOD such as RFB1.52 installed, JSGME is displayed by the task manager, "There is no response".
However, it will be suddenly displayed by the task manager in about ten minutes when seeing as it is, "Be executing it".
Time until being displayed, "Be executing it" changes by MOD that tries to be installed.
It took about 40 minutes until the task manager changed into the display of "Be executing it" when "Spax's SH4 Uboat Speech FIX v8" was installed.
When "DBSM" was installed when "OpsMonsun v705" and "New Real Environment mod" were installed, time was necessary by about 30 minutes.
Similar time was necessary though "DBSM" was previously installed or it installed later.
Why is it displayed, "There is no response", and the cause is uncertain.
In a word, there is no problem in "DBSM".
It is possible to install it though time is necessary.
I think that it is my personal computer that the problem is.
Mr. Steve. I'm sorry.
The bad one is me.I am bad.
It was necessary to confirm it accurately.
The report is ended.
In the future, it will expect it of MOD that you made.
