Roland r706 installer problem

I have problem with my disk installer, advice please

My machine is roland R706+LV

Thanks before

 

Wrong disk, corrupt disk !?

 

But when I check it and open with msdos the all files and folder its fine and can read normally

 

When installing LEITSTAND, do not use the MMS disk. Judging by the photo, you need to insert a language disk or a configuration disk

 

Never put original Roland disks into a Windows computer. Diskettes are formatted differently and have hardware copy protection. If a disk fails the check, it can only be repaired with a specially written program, or a new one can be purchased from Roland. Any attempt to restore it with DOS or WINDOWS programs will result in destruction.
The diskette in the photo is normal to give such a message if it is used to install the RCI program. It is used ONLY to reinstall the MMS firmware.

 

You can try it with another version, v20.03

 

So what disk should i use, can you give me the disk sequence
I'm did it with this sequence :
1. Disk leitstand 1, 2 and 3 then
2. Disk sprachen deutsch and then sparchen english
3. Disk sps-mms-config
4. Disk machine number
Is it right...?
Cause when in step 3, i got message like the picture i sent

 

Step 3 should be machine configuration. The diskette has the machine number. Not MMS config.
As Sergey has shown above

 

Don't use the SPS-MMS config disk unless you are going to install the MMS program

 

Ok, i will try again
Thanks u very much

 

It's work, i pass the step 3 as sugested and runing well

Thanks all
