Building Databases error at 99%

[pimpsv]

I keep receiving the same error with Armory installing. Has there been found a solution to this problem yet? I do not know what to do anymore. Already installed two times at two different computers..

It says: "Missing headers" and that I should close the program etc.

Is there an option to retreive my waller another way? I only have the root key.

Many thanks in advance.

Are you using 0.93?

[pimpsv]

Yes. Previous time I installed 0.96 but that did not work either (got stuck somewhere during installation).

I use windows 7 therefore I thought I should use the older version. On the Armory website it also says under version 0.93 that it works with windows 7 (64 bit).

[goatpig]

Delete this folder:

C:\Users\Pim\AppData\Roaming\Armory\databases

Then use 0.96

[pimpsv]

Okay, so now I get this error:

And when I installed 0.96 on my other laptop, I get this message at 99% scanning transactions:

What to do?

[goatpig]

Same issue as you had before, one of the last few file in your blockchain data folder is corrupt.

You want to delete file 891 and later, start your node and let it fix itself. Then you can wipe Armory's DB and try again.

[pimpsv]

But Bitcoin Core itself is working properly. Only with Armory I got an error.

It is required to use 0.96? I have the feeling that it does not work on my windows 7 laptop as my whole computer gets SUPER slow during installation (which is not the case with the 0.93.3 software). Note that the computer is not that bad (i7, nvidia 6400 etc.).

Or can I also use 0.93.3 with windows 7? And secondly, do I understand you correct:

1. delete rev00891.dat t/m 00893
2. start Bitcoin Core
3. start Armory 0.93.3

?

Many thanks in advance.

It is required to use 0.96?

You should always update when possible. Use the testing build for 0.96.1:

https://github.com/goatpig/BitcoinArmory/releases/tag/v0.96.0.2-testing

Note that the computer is not that bad (i7, nvidia 6400 etc.)

The relevant factors are, in the following order:

- storage speed
- core count
- ram

Since your graphics card is low end (x400 for nvidia is as bad as it gets), I'm guessing your computer is short on RAM and uses a HDD.

Or can I also use 0.93.3 with windows 7

It won't be able to run on the SegWit chain when that comes around. It also has some security concerns seeing it still uses the phone home code.

1. delete rev00891.dat t/m 00893
2. start Bitcoin Core
3. start Armory 0.93.3

More like

Code:

1. delete blk00891.dat through 00893 (don't care about the rev files, they're generated on the fly during indexation)
2. Start Core, let it sync
3. Delete Armory's DB
4. Run Armory

Thanks for the info sir, already very helpful (and interesting). I will try the steps as described.

FYI I looked up the exact specs:

• Intel® Core™ i7-2670QM processor
  6 GB DDR3 SDRAM
  NVIDIA® GeForce® GT555M DirectX® 11 2048 MB (although irrelevant)

Guess it is a HDD and not SDD, but a little better graphics.

Will post an update after steps tried!
